Edit and post Jon
Yes the entire page is here but I only need you to do one problem so should only take a few minutes.

12. The events X and Y are mutually exclusive. Suppose P(X) _ .05 and P(Y) _ .02. What is the probability of either X or Y occurring? What is the probability that neither X nor Y will happen?
18. Let P(X) _ .55 and P(Y) _ .35. Assume the probability that they both occur is .20. What is the probability of either X or Y occurring?
44. 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 information 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.

20 up to 50 100
50 up to 100 75
100 up to 200 75
200 or more 50
Total 500
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?

It is used not just for diagnosis, however, but also for billing, access to services, and legal cases. Not all practitioners are in agreement with the content and structure of the  DSM-5-TR , and dissociative disorders are one such area. These disorders can be difficult to distinguish and diagnose.
