Homework Help: Math

Posted by Punkie on Wednesday, November 18, 2009 at 5:32pm.

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.
b. The first is a girl and the second a boy.
c. Neither is a girl.
d. At least one is a girl.

I was wondering about the formula....

is a. P(probability) = 1/2(boy) + 1/2(boy)
P = 1/2 + 1/2
so P = 2/2
to me this doesn't seem right
