Answer:
Let the G represent the Girl child
and, B represents the Boy child.
Then Sample Space = {BGG, GBG, GGB, BBG, BGB, GBB, BBB, GGG}
Thus, There are 8 sample space.
Then, Probability that couple have 1 boy = {BGG, GBG, GGB}
= 3 ÷ 8 = 0.375
Probability that couple have 2 boys = { BBG, BGB, GBB}
= 3 ÷ 8 = 0.375
Probability that couple have 3 boys = {GGG}
= 1 ÷ 8 = 0.125
