Question: 1. A psychologist determines that the probability of relapse in her clinic is p = .12. Assuming independent outcomes, what is the probability that two of her patients relapse?
2. The probability that a student in college will "experiment" with drugs is p = .31. The probability that a college student will not experiment with drugs is q = .69.
(a) What type of relationship do these probabilities have?
(b) A student heads off to college. What is the probability that the student experiments with drugs or does not experiment with drugs?
