Question

Why P(3 sets and V wins) = (0.09+0.0675)? The formula for the probability of the intersection of two events A and B is P(A) * P(B). But, why did we add (0.09+0.0675)?

Part (a):
The possible outcomes are listed below, organized by who wins the match. Within each match winner
category, who wins each set is shown.
1)
11)
Player V wins:
vv
VMV MVV
Player M wins.
MM MVM VMM
Part (b):
The ways in which Player V can win a match against Player M and the corresponding probabilities are
shown below. Adding the probabilities for the various ways Player V wins the match yields the overall
probability of 0.4575.
Outcome

Probability
(0.5)(0.6)=0.3
(0.5)(1 -0.6) (0.45) = 0.09
(0.5)(1 0.7)(0.45) = 0.0675
Total: 0.3 + 0.09 +0.0675 = 0.4575
Part (c):
P(3 sets | V wins) =
P(3 sets and V wins) (0.09 +0.0675)
P(V wins)
0.4575
0.1575
≈ 0.344

In women's tennis, a player must win 2 out of 3 sets to win a match. If a player wins the first 2 sets, she wins the
match and the third set is not played. Player V and Player M will compete in a match.
What is the probability that a match between Player V and Player M will consist of 3 sets given that
Player V wins the match?
