a) There are 8 possible combinations and each probability is 1/8.
b) The probability that it is a boy given that there are two girls is 3/8

a) The sample space is given by:
BBB (3 boys)
BBG (Boy, boy, girl)

BGG (Boy, girl, girl)
GBB (girl, boy, boy)
GBG (girl, boy, girl)

BGG, GBG, GGB
So the probability is given by:
P(BGG ∪ GBG ∪ GGB)=
