Let x be the number of courses for which a randomly selected student

1. 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: x 1 2 3 4 5 6 7 p(x) .04 .02 .08 .26 .35 .14 .11 (a) What is P(x = 4)? P(x = 4) = (b) What is P(x 4)? P(x 4) = (c) What is the probability that the selected student is taking at most five courses? P (at most 5 courses) = (d) What is the probability that the selected student is taking at least five courses? more than five courses? P (at least 5 courses) = P (more than 5 courses) = (e) Calculate P (3 x 6) and P(3 < x < 6). P (3 x 6) = P (3 < x [removed] μx) = 10. In a probability model, which of the following numbers could be the probability of an outcome? (Select all that apply.) 2/3 1/4 -1/4 1.4 0 3/4
