Hi, There are two tennis players. Player A wins a point 50% of the time (against any rival), while Player B wins a point 60% of the time against any rival. That is P(A) = 0.50 and P(B) = 0.60. If Player A plays with Player B, what is the probability that Player A beats Player B, i.e. P(A, B) and the probability that Player B beats Player A, P(B, A) ? I am not sure how I should simulate this problem. Thanks, MG.
