Let x be the number of courses for which a randomly selected student at a certain university is registered. The probability distribution of x appears in the table shown below. p(x) 0.04 0.05 0.08 0.24 0.37 0.15 0.07 (a) What is P(x = 4)? P(x = 4) = X [b) What is P(x s 4)? P(x = 4) = X (c) What is the probability that the selected student is taking at most five courses? X 'd) What is the probability that the selected student is taking at least five courses? 0.59 e) What is the probability that the selected student is taking more than five courses? X
