Question

If a number a is chosen at random from the set

of positive integers less than 20, then what is the
probability that 12/a > a?

A. 12/19
B. 3/5
C. 7/19
D. 3/19

Answer 1

D. 3/19

Explanation:

12/1 = 12

12/2 = 6

12/3 = 4

These are the only ones that make the equation true.

There are also only 19 numbers because they need to be less than 20 like the question indicated. Therefore, the answer is D.
