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:
(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 < 6) =
