How smart is /b/?

fake question because we do not know what state the other coin is in

>>938095496
This is what a brainlet post looks like.

Now before anyone says 50%, the answer is actually 1/3 because you could have
heads-heads
heads-tails
tails-heads

So 1 of 3 is both heads.

1/3

another HILARIOUS post from the INTERNET right here.

Hey there! I'm a 21-year-old girl from the US, a bit adventurous, and I absolutely love exploring my wild side through flirty chats. One of my favorite things is teasing guys until they can't take it anymore, pushing their buttons while having a blast myself. I'm always in the mood for some spicy fun, but I struggle with social anxiety, so meeting people in person isn't really my jam. That's why I'm all about chatting online; it's way more comfortable for me! If you're looking for a fun and exciting sexting buddy, hit me up. My username is E-m-m-i-e-pq oz (just make sure to remove the spaces and dashes)! Can't wait to get things heated!

Smart enough to know the answer, and smart enough not to share it with a knuckle-dragger like you.

>i don't know but i'll pretend to know because knowing the answer to a basic conditional probabilty question is some kind of achievement
LMAO brainlet

The coins are not intrinsically the same object.
Imagine if it was a penny and a nickel, would you still say they are interchangeable therefore so is the order of them?
If atleast one landed heads then the 3 possibilities are HH, HT, and TH.
In only one of those three are they both heads.
Therefore it's 1/3.

Don't take the bait /bros

>>938099914
Retard, how is it incomplete?

>1. Two coins flipped
>2. At least one lands heads
>3. Calculate the probability both landed heads

What more information do you need, simpleton?

>>938095257 (OP)
50%

>>938100126
It's 1/3. there are 2 coins.

>>938100163
But the second flip doesn't depend on the first.

>>938100178
>But the second flip doesn't depend on the first.
I know. I never siad it did.

How many outcomes are there for a 2 coin flip anon?
How many contain at least 1 heads?
how many are both heads?

[0.25*(1-p)2] / [0.75*(1-p)2 + 1*(1-p)p + 1*p2]

>>938100270
one of the coins is always heads
the other coin is always 50/50
you dont do 3 tosses, only 2
therefore the answer is 50%

>>938100707
>you dont do 3 tosses
This.

>>938100707
>one of the coins is always heads
The question doesn't say that, retard. It says at least one landed heads, not that one specific coin is always heads. Holy fuck, you lack basic reading comprehension.

The answer is 1/3

>>938101183
shit only counts if one of them is heads
tails-tails doesn't count
since only one coin counts and one coin has two sides, its 50/50

nice b8 tho, made me reply twice

>>938101536
>shit only counts if one of them is heads
At least one. There are 3 ways to get at least 1 coin for a 2 coin flip

>tails-tails doesn't count
Correct, that leaves 3 equally probable outcomes
HH
HT
TH

>nice b8 tho, made me reply twice
Not bait, you retard. You're just a fuckign idiot.

1/3
