On landed heads.
There is 50% possibility that the other one will also fal flat
Right?

50/50

The one is already heads and will always be heads as the question states it's heads.

You are just flipping one coin. So 50/50

>>724027597
>>724027648

Wrong.

>>724028049
At least one landed heads. Could be either coin. Could be both.

>The one is already heads and will always be heads as the question states it's heads.

Wrong. At least one is heads. Could be either coin, meaning either coin could be tails, just not both at the same time.

>You are just flipping one coin. So 50/50
Wrong. 2 coins were flipped. At least 1 landed heads. 3 equally likely ways to get at least 1 heads.

1/3 is the correct answer.

I thought it was suppose to be 49/50 with a 1% chance to land on the edge of the coin.

-0 because nothing ever works out for you anon, and you know this. You're not included in any parties and you've only an imaginary girlfriend, who Tyrone is probably with right now as we speak.

1/3

>>724027190
What if the coins were irregular. Would the answer change?

>>724028344
oh look an idiot.

1 is always heads. It doesn't matter if it's been flipped or not the outcome is heads.

Coin - Coin
Heads - Unknown

There is only one unknown. You flip for that unknown as one is certainly heads.

It is 50 50 as there is one unknown and the outcome is half the possible outcomes.

>>724027357
This.
Given that one of them is heads, the coins could land either:

TH, HT, or HH.

One out of three of those is two heads. Try harder

Mathematical statistics 101, welcome to elementary school kids.

>>724027190
Some Jew stole my coins. I can't answer the question

>>724028606

Or, to look at it another way.

There are four possible outcomes:

TT, HT, TH or HH.

So HH has a 1/4 chance of being right. But OP has stated that it is NOT TT. So we can discount that. Which leaves us with 1/3.

1/2 or 1/3 depending on how you take the question/

>Coin - Coin
>Heads - Unknown
>There is only one unknown.

You really shouldn't call other people idiots when you can't do basic conditional probability.

Here are all possible and equally likely outcomes containing at least 1 heads coin.

coin1 - coin2
Heads - Heads
Heads - Tails
Tails - Heads

All 3 contain at least 1 heads. All 3 are equally likely. Both heads is 1 of those 3

1 of 3

Always 50/50.

Shit, I had this in statistics a year ago

>>724029277
technically not true it has like a 51/49 chance favoring the side that was facing up during casting

1/2 or 1/3 depending on how you SUBJECTIVELY interpret the question posed.

I fucking hate this place and all younatupid shits in it.

Next you'll be trying to tell me that it's possible for minorities to be racist towards whites.

Assuming one coin will always flip Heads. The other coin will have 50/50. Depending on which country's coin the head side might be heavier, the newer coins with Queen Elizabeth on it have a higher chance of landing on tails because her face is slightly heavier. But the percentage it actually effects is too hard to find out.

>Assuming one coin will always flip Heads.

Why would you assume that?

>How smart is /b/?

yes

>>724030818
Because its in the fucking picture?

TWO COINS WERE FLIPPED. ONLY ONE WAS HEADS! THE OTHER WAS TAILS!

ITS 0% FFS!

>>724027190
50%
1 already landed heads that means that there only 1 coin with 2 sides that means 50/50 chance of heads and having 2 heads.

>>724027190
What are we figuring in for probability of the coin landing on its edge and registering neither a head or a tail?

>>724031473

Are you trolling or retarded?

>>724033336

No. At least one landed heads out of a 2 coin flip. There are 3 outcomes which satisfy this condition.

HH
HT
TH

1/3

>>724034198
That probability is so low that it is negligible.
