A contraceptive has an actual effectiveness of 82%. Over the course of one year, how many couples out of 100 using this method will become pregnant? Group of answer choices

a. 82

b. 24

c. 18

d. 64

c. 18

Explanation:

Given that the contraceptive has an effectiveness of 82%, I am assuming this implies that 82% of 100 or 82 couples will not get pregnant which leaves 18 couples left who will. This math simply involves subtraction of the total couples from the total couples multiplied by the percent effectiveness: total # couples - % effectiveness × total # couples.

100 - 82% of 100 = 100 - 82 = 18
