Get on the boat! A small ferry runs every half hour from one side of a large

Question:

Get on the boat! A small ferry runs every half hour from one side of a large river to the other. The probability distribution for the random variable Y = money collected (in dollars) on a randomly selected ferry trip is shown here.

Money collected 10 15 20 25 Probability 0.02 0.05 0.08 0.16 0.27 0.42

a. Find P(X > 20). Interpret this result.

b. Express the event “at least $20 is collected” in terms of Y. What is the probability of this event?
