Berdine's Chicken Factory has several stores in the Hilton Head, South Carolina, area. When interviewing applicants for server positions, the owner would like to include infor- mation on the amount of tip a server can expect to earn per check (or bill). A study of 500 recent checks indicated the server earned the following amounts in tips per 8-hour shift.

a. What is the probability of a tip of $200 or more?

b. Are the categories "$0 up to $20," "$20 up to $50," and so on considered mutually exclusive?

c. If the probabilities associated with each outcome were totaled, what would that total be?

d. What is the probability of a tip of up to $50?

e. What is the probability of a tip of less than $200?
