(iii) 79% of students attending private colleges and universities graduate in 4 years.

What is the probability that a randomly chosen student attended a private school and graduated in 4 years?

a.) .55 / .79 = .6962

b.) .20 / .55 = .3636

c.) .20 / .79 = .2532

d.) .55 * .79 = .4345

e.) .20 * .55 = .11

f.) .20 * .79 = .158
