A couple is planning on having three children. You may assume
that one child
is born at a time (no twins or triplets), that each child was born
two years apart from
one another, and that it is equally likely for the couple to have a
boy or a girl.
Construct a tree diagram and show the sample space.
a) What is the probability that the oldest child is a girl and the
two younger
children are boys?
b) What is the probability that the couple has one girl and two
boys?
