Consider the chance experiment in which both tennis racket head size and grip size are noted for
Question:
Consider the chance experiment in which both tennis racket head size and grip size are noted for a randomly selected customer at a particular store. The six possible outcomes (simple events) and their probabilities are displayed in the following table:
a. The probability that grip size is 4(1/2) in. (event A) is P(A) = P(O2 or O5) = .20 + .15 = .35. How would you interpret this probability?
b. Use the result of Part (a) to calculate the probability that grip size is not 4(1/2) in.
c. What is the probability that the racket purchased has an oversize head (event B), and how would you interpret this probability?
d. What is the probability that grip size is at least 4(1/2) in.?
