No. of students transferred from 2-yr. community college = 34.
Probability of selecting 1st student , P(A) = 34/100 = 17/50.
Probability of selecting 2nd student, P(B) = (34-1)/(100-1) = 33/99 = 1/3.
Hence, the probability of selecting both the students from 2-yr. community college will be = P(A)P(B)
= (17/50)*(1/3)= 17/150
