Question 936608
the probability of A passing the exam is 3/5 = .6
the probability of A failing the exam is 2/5 = .4


the probability of B passing the exam is 4/5 = .8
the probability of B failing the exam is 1/5 = .2


the probability of both students passing the exam is .6 * .8 = .48


the probability of only A passing the exam is .6 * .2 = .12


the probability of only one of them passing the exam is .6 * .2 + .4 * .8 = .12 + .32 = .44


the probability of neither passing the exam is .4 * .2 = .08
