How smart is Cred Forums?

33% due to wording

1/2
where is my harem
they told me smart gets bitches later
when is later

one coin is given
so there is really just one coin toss

You're retarded.

50 percent. >_>

If one coin landed on heads, as you said, there's a 50/50 chance the other will also land on heads.

50% chance

It either happens or it doesn't

Incorrect.

>>_>
getout

Wrong.

explain faggot

Not really. It could be the first coin that hits heads or the second coin that hits heads. Both are distinct possibilities.

So far, only 1 correct answer.

Cred Forums is either underage or buttfuck retarded.

Or you're getting fucked with

Wow Cred Forums is dumb as fuck

>regular
>not american currency
why bother

fuck that explains my shit life

either the first one is heads and the second is tails, the first one is tails and the second is heads or their both heads, so 33%?

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

breh given that one of them hits head no matter what, its basically asking you flip two coins. At least one of them is heads, what is the chance the other coin is also heads?

It's more like 's image.

Flip two coins and remove any double tails you get from the results pool.

50% learn Bayes materrace, frequentist faggot

...

>solved a question for 4th graders
>smart

Let's do this without the additional limiting condition first:
HH
HT
TH
TT

The probability of both landing heads is 1/4 or 0.25.

Now since we know that at least one of them landed heads we're left with:
HT
TH
HH
It's now 1/3 or 0.33...

.25 is the chance, or 25 percent.

Im a Stats major, so think of this as an easy answer.

You're still wrong. Both sides on the controversy (.5 or .333...) will tell you that you're wrong and it#s true.

is there a comma missing guys???
lol how smart is Cred Forums
>bitches love sucking cock, dick and balls.

A Stats major that doesn't understand elementary statistics? I would sue your college/university if I were you.

REAL THREAD

1 million regular coins were flipped. What is the probability that all of them landed heads given that 999,999 of them landed heads?

you guys are all retarded...

>H - H => 1/4
>H - T => 1/4
>T - T => 1/4
>T - H => 1/4

We remove T - T because at least one coin landed head.

>H - H => 1/4
>H - T => 1/4
>T - H => 1/4

now we remove H - T and T - H because both coins have to land head

>H - H => 1/4 = 0.20%

now fuck off and go learn mathematocs from basics you stupid fuckers

Due to gamblers fallacy I think that it's a near 0% chance that the millionth coin is heads.

HT and TH are the same outcome. One is heads and the other is tails. The order in which they land has no effect on the probability. Given that one will definitely be heads the probability they both will be heads is 1/2.

You think you're being smart by implying the Gambler's fallacy.

However, you are assuming that the FIRST 999,999 coins flipped landed heads, and that there is just 1 more flip, thus 1/2.

But the OP question does not assume any first coin, there are 3 equally probable ways to get at least 1 heads coin for a 2-coin flip. 1 of those ways is both heads

1/3

Answer this question.

3 coins were flipped. At least 2 landed heads. What is the probability that all 3 landed heads?

>HT and TH are the same outcome.

You're retarded.

25%!~

The question states 2 coins were flipped. It doesn't say a coin is flipped after another coin is flipped. If they are flipped at the same time you have 3 possibilities. Both are heads, one is heads and the other is tails, and both are tails. If you remove the possibility that both are tails you only have 2 outcomes, making the probability 1/2. Dumbass.

>The question states 2 coins were flipped.
Correct.

>It doesn't say a coin is flipped after another coin is flipped.
Correct, not that it matters anyway.

>If they are flipped at the same time you have 3 possibilities.
Well, technically you have 4 possibilities (HH, HT, TH, TT)

>Both are heads, one is heads and the other is tails, and both are tails.
Yes, as long as you understand that there are 2 WAYS to get one heads, one tails.

>If you remove the possibility that both are tails you only have 2 outcomes
A one heads, one tails result is TWICE AS LIKELY as a both heads result.

Flip 2 coins. According to your 3 outcome scenario, you have:

HH = 1/4
HT/TH = 1/2
TT = 1/4

Remove TT and you're left with

HH = 1/3
HT/TH = 2/3

1/3.

Dumbass
