Out of the 30 college students who visited campus health center yesterday, 9 receieved prescriptions while the remaining 21 did not. The following table further categorizes these 30 students by gender: Male (M) Female (F) Total Prescription (P) 6 3 9 No prescription (N) 9 12 21 Total 15 15 30 a) using the data from the table, estimate P (N) (probability of "no prescription" out of all sampled students) and P (M) (probability of "male" out of all sampled. b) using the data from the table, find P (N and M) (probability of no prescription and male) c) based on (a), what would P (N and M) be if the events N and M were independent? Compared to the answers you got in (b), do you think N and M are independent?
