A fair coin is tossed three times. What is the probability of obtaining one Head and two Tails?

Question

parthkohli · Answer

First, there are in totality $2^3 = 8$ different kinds of outcomes. Now you have to find the number of ways that you could arrange one head and two tails.

anonymous · Answer

it is 3so the probability is 3/8
but my question is
tossing a coin is one independent even

anonymous · Answer

so the probability of get a head is 1/2 and a tail is 1/2
so why the probability is not (1/2)(1/2)(1/2) ?

parthkohli · Answer

The probability is not (1/2)(1/2)(1/2) because it is not given that we have to find the probability of HTT.

But we have to find the probability of getting two tails and a head, which can happen in these ways as well:

THT
HTT
