MCAT Question A Day - 5/4/13 - Answer!

The probability of parents having a daughter is 50%. What is the probability of parents having three daughters in a row?

A.  1/2
B.  1/4
C.  1/8
D.  1/16

The correct answer is (C). The chance of having a daughter is 1/2, but the chance of having two daughters in a row as independent events is 1/2 x 1/2 = 1/4.  Similarly, the chance of having three daughters in a row would be 1/2 x 1/2 x 1/2 = 1/8.
