50%

50/50

42, it's always 42.

33%

75%

Retards detected.

Another tard.

48.7%.
The heads side of a coin is marginally heavier, therefore tails shows up just a little bit more often.
Some students wasted time researching it.
Google it if you don't believe me.

0% because they're euros

Another retard thinking he's being clever but completely fucking up the answer.

Additionally. One coin is allready heads, so it's not really part of the equasion. Therefore we're only concerned with the probability of the second coin. So the above percentage is correct.

1/3, douche canoes.

>Additionally. One coin is allready heads, so it's not really part of the equasion

Complete fucking retard.

Read the question.

89%

trying too hard

100%

What? Are you dumb?

H - H (50%) (Given one is heads)
\ T (50%)
T - H X (0%)
\ T X (0%)

1/4

holly shit guys...

Agreed.

The problem is that you're not trying hard enough, you fucking simpleton.

The answer is 1/3.

1 in 3, retards

50/25

HH 1/3
HT 1/3
TH 1/3

Answer = 1/3.

ITT: Retards can't into conditional probability.

> (You)
Whaaat? You never read books, do you?

42

1/3

You fucking idiot. You can't get tails heads because the first one is already heads. The only possible outcomes are heads tails and heads heads, making it 50%

Yet another classic thread, where OP tries to be clever.
The interesting part is, that anyone past high school knows this is 1/3. And everyone knows, that the only reason OP posts this, is because he was stupid enough to answer 50% himself, and now tries to find underaged people to answer wrong, so he himself can feel better about himself...
*golfclap*

>says it's 33%
>replies to everyone who says 50% with "tard"
>never justifies logic

>the first one is already heads.

No it isn't retard.

AT LEAST one coin landed heads, not THE FIRST coin.

HH
HT
TH

1/3

Congratulations, you're retarded.

You forget one thing, the first coin is a 50/50 chance to get heads, you can't just ignore that 50% in your calculations.

"At least one is heads", not the first one. Meaning it can be tails heads, heads tails, or heads heads

This, so much this

>>never justifies logic

Maybe you missed these posts

And now this one.

Pic Related: 1/3

Depends on what side was up while it was flipped. It's more probable to land the same way

You guys,

With two coin flips there are four outcomes,

HH
HT
TH
TT

TT must be eliminated because there has to be heads. That leaves with three outcomes, one of which is HH. So, 1/3.

ITT: Retards get butthurt because they thought the answer was 50%

HAHAHAH retarded faggots.

Rather: ITT OP fucked up and thought it was 50%, now tries to justify his stupidity.

25% faggots because its half divided by 2

Which side is heads n a euro?

>this damage control

Exactly! :D
Silly OP

>Given one of the coins landed heads.

>people stil think the answer is 50%
>afraid to post because they will appear dumb as nigger shit

kek

50%

>at least one

Moron or troll?

My guess is both moron and troll.

61.66666%

20%
One of the coins could land on it's edge!

what kind of troll science is this?
the correct answer is 25%. you cannot just remove one result. this is not how probability works.

50/50

P(B) in this scenario is 1.0 you fucking moron.

Now, what is 0.5 / 1.0 ?

There is no conditional probability here you moron, the events are independent.

>this is not how probability works.

Goddamn, you are fucking retarded.
Conditional probability, user.

The probability of event A (both heads) given event B (at least one heads)

Probability of at least 1 heads for 2 coin flip = 0.75
probability both are heads for 2 coin flip = 0.25

0.25 / 0.75 = 1/3

In the pic, TT is removed from the sample space as it is no longer a possibility GIVEN AT LEAST ONE coin landed heads.

I can't believe people on Sup Forums are this fucking slow and retarded at math.

1/3 plebs

1/2
Source: i smart

You're retarded. Now explain your retardation so we can all laugh at how stupid you are.

Are you fucking retarded? H/T and T/H are the same fucking result you mong, you aren't flipping three coins.

One has already landed heads
This is now a one coin flip problem
As they are independant events the answer is 1/2

>One has already landed heads

There are 3 equally probable ways to get at least one heads.

There is 1 way to get 2 heads.

1/3.

>Claims knowledge of conditional probability theory.
>Completely ignores conditional probability theory in his "answer".

Is your father also your brother?

Its a trick question, purely mathematical answer is 33%, normal answer is 50% and if you want to get weird you can even get it to be 25%.

>H/T and T/H are the same fucking result

HAHAHAHHAAH get a load of this retarded faggot.

Yeah, man

penny = heads & quarter = tails

is TOTALLY the same result as

penny = tails & quarter = heads


HAHAHA you fucking mong

The answer is 1/3.

Tails-Tails: nope

Heads-Tails 1/5
Heads-Heads 1/5
Heads-Edge 1/5
Tails-Heads 1/5
Tails-Edge 1/5

The answer is 1/5

>3 equal ways to get at least one heads
>you're only flipping 2 coins

Wew lad

nice b8, m8

wew lad

HH
TH
HT
Are the outcomes if the order the coins are flipped is not random. So it's 1/3.

>is as retarded as Anita Sarkeesian
>unironically uses Sarkeesian gif

kek m80

I can't believe you're unbelievably retarded you are, 1 coin is heads guaranteed, the other is 50/50, leave your basement once in a while

Well if you have a coin on the floor that is heads and you flip another coin, it has a 50% chance of also being heads, anybody how doesnt understand that its a mathematican question will give 50% as an answer and its correct if you ignore the tricky mathematical side of it, nowhere does OP imply that its a math problem and he doesnt even explain how the first heads is produced.

33% if the two coins were different and/or were tossed in a certain order
50% if the two coins are the same and tossed at the same time

Anyone thinking its 50% should stop and think about it before posting retarded shit.

It's 1/3.

It's obvious most of these people haven't taken statistics, or don't know how to use their brain. It's 1/3

You can't be this dumb. You must be trolling.

>look at me I'm a developer


Kill yourself poor faggot

>It is a bernoulli experiment
(0|1)
>It is an unconditional probability
(couse each coin toss has 50% heads 50% tails)
I dont have to say more the solution is clear and easy. No need to shitpost.

>Well if you have a coin on the floor that is heads and you flip another coin, it has a 50% chance of also being heads

True. But that's a different scenario to OP question.

>anybody how doesnt understand that its a mathematican question will give 50% as an answer and its correct if you ignore the tricky mathematical side of it

How the fuck can an answer be correct and incorrect at the same time, you spastic?

The answer is 1/3.

>33% if the two coins were different and/or were tossed in a certain order
>50% if the two coins are the same and tossed at the same time

How can you be this fucking stupid?

Why is Sup Forums so retarded? It says at that one is a guaranteed heads. So the only variable is a single coin which has a 50/50 chance of being heads. It's 50%.

>able to write a simple simulation of conditional probability question
>developer

wew lad, your retardation is showing.

I guess being able to use MS paint makes you a CAD expert too.

fiddy bercent :-DD

It's 1/3, right? h/t does not equal t/h even if the two coins are of the same type

No, dumbass.

2 coins, 4 possible outcomes:

HH
HT
TH
TT

At least 1 landed heads.

TT is no longer possible, leaving:

HH
HT
TH

HH is 1 of those 3

1/3

>True. But that's a different scenario to OP question.
We dont know how the first heads is produced, so how can you say its different? He might just be placing a coin on the floor with the heads side up and then flipping the other coin. All we know is that 1 side is quaranteed to be heads and if you flip 2 coins at the same time 1 coin has to have 2 heads or it will not be quaranteed anymore.
If you ask me, you need to know how the guaranteed heads is produced before you can tell me that the answer is ONLY 33%.

>It's 1/3, right? h/t does not equal t/h even if the two coins are of the same type

Correct, user. See some of the explanations in this thread. Also,

Pic Rleated: 1/3

it was never said the order was relevant you autistic shits
HH
HT = TH

50%

There are never 4 possible outcomes. There are only two. Heads and Tails. Heads and Heads. The question is the odds both landed heads. One is guaranteed to be heads. TH and HT are not independent results. They are literally the same result. You are fucking retarded.

>We dont know how the first heads is produced

>two coins were flipped
>at least one landed heads

Seems pretty fucking clear to me, you spastic.

>so how can you say its different? He might just be placing a coin on the floor with the heads side up

>2 coins were flipped
>at least one landed heads

Are you learning yet, simpleton?

1/3

(11..10..01..00) 00 is cross out coz ther is 1 head at least so 11 is 1/3 of possible outcome

>HT = TH

Holy FUCK you are dumb as pig shit.

If you think that:
penny = heads & quarter = tails

is TOTALLY the same result as

penny = tails & quarter = heads

Then you should kill yourself.

Answer = 1/3

Yeah, but what if one of the coins lands on its' edge?
Coins are 3-dimensional objects.

Wouldn't that make it 1/5, not 1/3?

>Heads and Tails. Heads and Heads.

And tails and heads

3 equally probable outcomes.

HH is 1 of them

1/3

>TH and HT are not independent results.

Oh God, another fucking simpleton.

If you think that:
penny = heads & quarter = tails

is TOTALLY the same result as

penny = tails & quarter = heads

Then you should kill yourself.

Answer = 1/3

Cry moar.

Did he flip them at the same time untill atleast 1 of them landed heads? If so the answer is 33%.
Did he throw them separately and checked the first coin to be heads to avoid a situation of 2 tails? Or does 1 of the coins have heads on both sides?

>Yeah, but what if one of the coins lands on its' edge?
>Coins are 3-dimensional objects.
>Wouldn't that make it 1/5, not 1/3?

No, because the probability of the coin landing on it's edge is negligible.

To be pedantic, the answer is approx. 1/3

what is she looking at?
1 is always heads.
the other one can be H or T. so that's 50%.
