Explanation / Answer
a) Probability that there are exactly 3 girls is represented by: GGG
Probability = 1/8 = 0.125
b) Probability that there are exactly 2 boys can happen in 3 ways: BBG, BGB, GBB
Probability = 3/8 = 0.375
c) Probability that there are exactly 0 boys = Probability there are exactly 3 girls
Probability = 1/8 = 0.125
