Use the following notation for the various events: N = Nurse, D = Doctor, PN = prefer new procedure, PO = prefer old procedure, NP = no preference. Find out the following probabilities for a person selected at random from this sample of 400 people.

1. P(N), P(D), P(PN)
2. P(N, given PN), P(D, given PN)
3. P(PO, given N), P(PO, given D)
4. P(N and PN), P(D, and NP)
5. P(PN or NP)
6. Are the events PN = prefer new procedure and NP = no preference mutually exclusive? Why or why not?
7. Are the events PN = prefer new procedure and NP = no preference complementary events? Why or why not?
8. Are the events N = nurse and PN = prefer new procedure independent? Why or why not? Validate using the formula that is used to show if two events are independent or not.
