What is the probability for a family with three children to have a girl and two boys (assuming the probability of having a boy or a girl is equal)? Answers
A) 1/8	B) 1/4	C) 1/2	D) 3/8	E) 5/8
One possible case is: girl - boy - boy   The probability of this is 1/2*1/2*1/2= 1/8   There are 3C2 = 3 such cases so we should multiply by 3.   P(one girl and two boys) = 3/8   The answer is 3/8.
