What is the probability of tossing three coins and having exactly one of them show tails?

Question

anmolsingh · Answer

the possible outcomes of such a toss are given as 2^(no of coins or tosses)=2^3=8
now there will be 3 times when each coin shows EXACTLY 1 TAIL. so the probability is 3/8

When the sample space is small and you're lazy, you can always list all the possibilities and count:

HHH
HHT*
HTH*
HTT
THH*
THT
TTH
TTT

3/8
