If a student is selected at random, what is the
probability that the student receives aid
(rounded to the nearest percent)? [? ]%

Answer 1

Explanation:

a probability is always the ratio

desired cases / totally possible cases

in our case the desired cases are all students with financial aid : 6101

and the totally possible cases are 10730.

so, the probability to pick a student at random, who receives financial aid is

6101 / 10730 = 0.568592731... = 56.8592731...% ≈

≈ 57%
