Students are given three chances to pass a basic skills exam for permission to enrol in Calculus. Sixty percent of the students pass on the first try, of those that fail on the first try, fifty four percent pass on the second try, and of those remaining, forty eight percent pass on the third try.

a.What is the probability that a student passes on the second try?

b.What is the probability that a student passes on the third try?

c.What is the percentage of the student pass?

Can someone help me with this? I don't know how to solve it. Thank you!
