0.25% chance

1/4 obviously

Stupid faggots.

read the question and try again.

50%

over 9000

Are Sup Forumstards really this stupid?

My entire dick. That's the answer.

It's a 1 in 3 chance.

75%

It's 33.3333..% (phasespace with one coin being heads is [H,T], [T, H], [H,H] - ergo 1/3)

50%

the jews did this

Only correct answer so far.

So it's not 50%? I was always weak with probability

I think you know what needs to be done to them.

I can't believe how retarded you all are

>So it's not 50%?

No. it's 1/3.

Its Faggot%

or Faggot / Newfag

which can be simplified as:

33 point faggot faggot faggot


take ur fucking stupid ass math shit somewhere else, post tits,rekt,memes,CP, or get the fuck out

how

How can you be sure? Is it cause 999 when I turn my screen upside down is 666. Therefore you are the devil and a liar.

We have 4 different outcomes: (H,H), (H,T), (T,H) and (T,T). Somehow we now know that AT LEAST one of them if heads, which eliminates the outcome (T,T), leaving us 3 outcomes. Only 1 of these, (H,H) is "both are heads", hence the probability is 1 in 3 = 0,33 = 33 %.

the options are either:
heads -tails
tails-heads
or heads-heads

ergo 1 in 3

There are four possibilities - 1 tails, 2 tails. 1 heads, 2 tails. 1 tails, 2 heads. 1 heads, 2 heads. The first is ruled out, so the odds are 2/3.

Well first we have to establish what a "coin" is on a conceptual level.

What does "both" imply and how can we measure it?

>tits
>rekt
>memes
>cp

Which Sup Forums are you on? Cause it isn't this one.

No it said at least one of them landed heads

Sample space before condition:
{(HH), (HT), (TH), (TT)}

At least 1 landed heads. New sample space:
{(HH), (HT), (TH)}

HH is 1 of those 3

1/3.

It's obviously 23.6% that the other one is also heads.

3/4
[Heads, Heads] - [Heads, Tails] - [Tails, Heads] - Tails, Tails

and so they did,
had it been worded "the first always lands on heads" then yes it would be 50/50 as the coins are independant, but as it is worded it is 1/3

WHAT?

>No it said at least one of them landed heads

Yes, so he's right.

HH or HT or TH

1/3

Retards.

Answer = 1/3

Flip 2 coins. 4 equally probable outcomes
HH
HT
TH
TT

At least one landed heads, so TT is eliminated from the probability space, leaving three:
HH
HT
TH

HH is 1 of those 3.

1/3

Mathematically, we solve using Bayes' theorem:

This is a conditional probability question, so use Bayes' theorem to solve.
P(A|B) = P(A∩B)/(P(B))

Explanation for faggots:

COnditional probability questions take the form:
>What is the probability of Event A given Event B?

OPs question is
>What is the probability that BOTH coins landed heads, given that AT LEAST ONE coin landed heads?

So here

A = "both coins are heads" = {(HH)} = 1/4
B = "at least one coin is heads" = {(HH), (HT), (TH)} = 3/4

P(A|B) = P(A∩B)/(P(B)) = (1/4)/(3/4) = 1/3

Am I supposed to be taking notes?

How are you this stupid?

100%, head is easy to get.

THE ANSWER IS 1/2

ITS LITERALLY A COIN FLIP, THE SECOND COIN WILL LAND HEADS OR TAILS REGARDLESS OF THE FIRST COIN

It's really not. It's 3/4

Reread the question, dumbass.

impossible to tell as it's random chance

My copypasta.

Now I can retire from the internet having achieved my life goal.

You are a retarded

it's a given from the problem that one is a head, so yeah you are right, it's 50%
rest of people are brainlets who just try to blowjob themselves until their neck cracks leaving them just fine

Retard detected, guys.

Oh this again..... first one is heads - FORGET IT ! Its gone you could have had a fucking million and 1 heads in a row and it means NOTHING ! Flip the coin its 50/50 or 50% chance ! you must all be Murican's ?

Wrong

You're a fucking moron lol

The retard is trying to sound smart
Here's the obvious explanation : if it can be Heads and tails and one's always going to be heads it can be either head,tail / head,head / tail,head That's 1/3 since it's 3 outcomes aka 33.3333

>first one is heads

Wrong, dumbass.

1/3

Oh I thought it meant that, sorry English isn't my first language.
I thought it meant one coin always lands on that side

k-mart smart, nigga

lel XD :D >:(

>I thought it meant one coin always lands on that side

2 reguar coins were flipped and at least 1 landed heads.

It doesn't always land heads.

1/3.

kek you're still retarded lmao XD #dumbassIt's1/3

Its a 50 % chance you fucking idiots

100% probability that you're a fucking moron.

lolololol what a newfag 50% is the true alpha answer, everything else is le funny potato answer meme
>1/3
>not a retarded inbreed
pick one famalamalamalamalamamaallalamam

one coin landed head,
so there are 50% of probability that the second one lands head as well.

Correct, 10/10

1/3

If 1 coin is GUARANTEED TO LAND ON HEADS THEN THE OTHER COIN HAS A 50/50 CHANCE OF LANDING HEADS SO ITS A 50% CHANCE YOU IDIOT AMERICAN

morons

en.wikipedia.org/wiki/Bayes'_theorem

The more you post, the more we all see how dumb you are.

The answer is 1/3 of course.
