A couple plans to have three children. Find the probability that they will have:
a) All girls:: (1/2)^3 = 1/8
b)exactly two boys or two girls ::(3/8)+(3/8) = 3/4
----------------------------
c)all boys or all girls:: 1/8+1/8 = 1/4
-------------------------------------------
d)at least one child of each gender. 1-2(1/8) = 3/4
