Question

If a person visits his dentist, suppose the probability that he will have his teeth cleaned is 0.48, the

probability that he will have a cavity filled is 0.25, the probability that he will have a tooth extracted is

0.20, the probability that he will have teeth cleaned and a cavity filled is 0.09, the probability that he will

have his teeth cleaned and a tooth extracted is 0.12, the probability that he will have a cavity filled and a

tooth extracted is 0.07, and the probability that he will have his teeth cleaned, a cavity filled, and a tooth

extracted is 0.03. What is the probability that a person visiting his dentist will have at least one of these

things done to him?

Now, let C be the event that the person will have his teeth cleaned. Let F be the event of

getting cavity filled and E be the event of getting a tooth extracted.
