similar question, just want to confirm my answer:
The probability that a student graduating from Suburban State University has student loans to pay off
after graduation is .60. If two students are randomly selected from this university, what is the probability
that neither of them has student loans to pay off after graduation?

4/10 * 3/9 = 0.133
since the total # of students isn't given, just a percentage

then compute

.4*.4=.16
