The probability that a student will graduate with honors and get a good job is 0.09 whereas the probability that a student will graduate with honors is 0.1. What is the probability that a student will get a good job if she graduates with honors?
A
90%
B
9%
C
0.9%
D
18%
Correct Answer: 90%
Probability of graduating with honors, P(H) = 0.1 Probability of graduating with honors and getting a good job, P(H∩J) = 0.09 Probability of getting a good job if she graduates with honor, P(J/H) = P(H∩J)/P(H) x 100% = 0.09/0.1 x 100 = 90%
