Question:

Ana is a dedicated Skee Ball player (see photo) who always rolls for the 50-point slot. The probability distribution of Ana’s score X on a randomly selected roll of the ball is shown here.

Score 10 20 30 40 50 Probability 0.32 0.27 0.19 0.15 0.07

a. Find P(Y < 20). Interpret this result.

b. Express the event “Anna scores at most 20” in terms of X. What is the probability of this event?
