In a family with two children, what are the probabilities
of the following outcomes, assuming that the birth of
boys and girls is equally likely?
a. Both are boys. (1/2)(1/2) = 1/4
------
b. The first is a girl and the second a boy. (1/2)(1/2) = 1/4
-------
c. Neither is a girl. (1/2)(1/2) = 1/4
------
d. At least one is a girl.
P(at least one) = 1 - P(none)
= 1 - (1/4)
= 3/4
