If you flip three fair coins, what is the probability that you'll get two tails and one head in any order?

OpenStudy (shaleiah):

@FortyTheRapper

OpenStudy (fortytherapper):

So, what are the chances of flipping a heads if you only flipped it once?

OpenStudy (shaleiah):

1/2

OpenStudy (fortytherapper):

So 3 flips would be 1/2, and then 1/2, and then 1/2 again. So that would be \[\frac{ 1 }{ 2 }*\frac{ 1 }{ 2 }*\frac{ 1 }{ 2}\]

OpenStudy (shaleiah):

Ah, 1/8

OpenStudy (fortytherapper):

Correct. I don't know if 1/8 is acceptable or if they want it in a percent

OpenStudy (fortytherapper):

@anthonyym May you confirm this

OpenStudy (anthonyym):

Sorry I'm not good with statistics, but the possible outcomes are (H=heads, T=Tails) are: HHH,HHT,HTH,THH,TTH,THT,HTT,TTT

OpenStudy (fortytherapper):

^ Yeah, that's a great way to put it

OpenStudy (fortytherapper):

And she wanted TTH

OpenStudy (anthonyym):

But it says in any order, so I'm guessing it's 3/8?

OpenStudy (fortytherapper):

Oh it does! Yeah, then 3/8. I didn't see that part for some reason
