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

Parth (parthkohli):

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.

OpenStudy (anonymous):

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

OpenStudy (anonymous):

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) ?

Parth (parthkohli):

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
