Find the probability that the student is a) A male student without scholarship b) A male student, given that the student has scholarship c) A female student or a student who receives presidential scholarship Question 2 Given a sample space with eventsA and B such that P(A) = 0.342, P(B) = 0.279, and P(A or B) = 0.601. Are A and B mutually exclusive? Are A and B independent? Question 3 Show that the mean for a binomial random variable X with n = 3 is 339
