- Sam and Joan are playing a tennis match.
Question 1:
Sam and Joan are playing a tennis match. If the probability of Sam's win is 0.59, then find the probability of Joan's win. A. 0.47
B. 0.36
C. 0.41
Feedback Let event A = Sam wins and event B = Joan wins. Then,
P(A) = 0.59
Since if Sam wins, Joan cannot win and if Joan wins, Sam cannot win, so we can say that the events A and B are mutually exclusive. Other than these two events, there are
no any other possible outcomes. So,
P(A)+P(B) = 1
0.59+P(B) = 1
P(B) = 1-0.59 = 0.41
P(A) = 0.59

D. 0.25
