Question 1203262
<pre>
(i) Find the probability that there is a winner of the match after exactly two
sets.

P(RR or AA) = P(RR or R'R') = P(RR) + P(R'R') = (0.6)(0.7) + (1-0.6)(1-0.25) =

0.42 +(0.4)(0.75) = 0.42 + 0.3

(il) Find the probability that Andy wins the match given that there is a winner of
the match after exactly two sets.

P[AA | (RR or AA)] = P[AA and (RR or AA)]/P(RR or AA) = P(AA)/0.72 = 0.3/0.72 =
30/72 = 5/12
