What is the probability for a family with four children to have a girl and three boys (assuming the probability of having a boy or a girl is equal)?	Select
A) 1/2  B) 1/3  C) 1/4  D) 1/8  E) 1/16
One possible case is: girl - boy - boy - boy   The probability of this is 1/2*1/2*1/2*1/2 = 1/16   There are 4C3 = 4 such cases so we should multiply by 4.   P(one girl and three boys) = 4/16 = 1/4   The answer is 1/4.
