can you explain

or are you a fuckhead

take me away bois

odd are 5 to 1 for horsebiscuit

The result of the first coin does not influence the result of the second. The odds are 50/50.

No matter how many times the roulette spins black it DOES NOT improve the odds for a red spin.

1/3 cuntards

50%

This. It's called the Gamber's Fallacy

HT TH HH so 1/3 you fucking imbreds

One them landed heads. The second coin will have a 50/50 chance of also landing on heads.

Yes that is what I am describing. There is absolutely no higher chance of the coin turning tails because the other turned heads. Thinking any different is fallacy ... and bad gambling

The options are tails-tails, heads-tails, tails-heads, heads-heads. Tails-tails is not possible. The chance is 1/3. The gambler's paradox does not apply since we are decidedly going for a certain outcome with two coins. The paradox applies only when you look at individual stats like roulette spins.

No. One coin already landed on heads. Read again.

Are you really that stupid? Read above it explains it beautifully

exactly, the first coin is already determined

Also, it's a fallacy, not a paradox

No, you are only accounting for one coin, the other coin has already been determined

It doesn't say when it lands on heads it just says it will. That means it could be on the first OR second flip faggot. It's 1/3

it's an independent variable, meaning the coin flips do not affect each other. therefore, the probability that the second coin will land on heads in theoretical probability is 1/2, or 50/50.

Read the question. It doesn't say when the coin lands on heads. It could be either the first or second flip. All you know is it will land on heads so it is 1/3.

1/2 dumbasses

Wrong

Why is everyone so wank at reading and probability

Possibilities are: HH || TT || TH || HT

Cases where "at least one of them landed heads" = HH || TH || HT

Only 1 / 3 times will "the other coin" be heads too.

More commonly I think you come across this as a game show with prizes or goats behimf doors or something.

Correct. Everyone else who says it's 50/50 is ultra retarded

This. 1/2 fags would be right if they said that it was given that the first coin landed heads.

Let H represent heads, T - tails.

Possibile cases for described situation are:

H/T
T/H
H/H

Out of 3, only is satisfactory. Therefore, it's 1/3.

75%

Gambler's fallacy only comes into play if it were to call out a specific coin. it does not specify which coin is at least heads, only one of them. What we DO have is a partial observation. so now you need to see what available probabilities there are. If we state 1 as heads and 0 as tails, we know that [0,0] can't be rolled because at least one must be heads. [1,0] and [0,1] are each individually valid as each coin has the choice of heads or tails. and then we have [1,1]. Given coins have equal chances of landing heads or tails, we see that, of the available options, only 1 in 3 options gives the [1,1] result. Thus, If I flipped two coins, observed a random one as heads, you can predict that the other coin has a 33% chance of being heads.

0.25 aka 25%

50%

aka 2500 out of 10000
aka 1 limb out of 2 legs and 2 arms combined to make 4 limbs
aka 3 slices plus a half a slice of pizza, where the pizza was sliced into 14 equal pieces

exactly user, don't forget to multiply with the "kekfactor"

25.5 percent. Heads as a 51 percent chance where as tails has a 49 percent chance if heads is down.

Retards

It's 1/3

Flip 2 coins. 4 results possible and equally likely

HH
HT
TH
TT

At least 1 landed heads, so only TT is no longer possible, leaving 3.

HH is 1 of 3 equally probable outcomes.

1 of 3.

1/3

are you on grass or something

are you fucking autistic

Not sure if the 50% faggots are trolling or actually retarded
