Of the team members who do not wear glasses, 30 percent of them are in the 10th grade.To the nearest whole percent, what is the probability that a randomly chosen member of the JV swim team does not wear glasses and is in the 10th grade?

A
14%
B
17%
C
55%
D
67%

Explanation

If 55% wear glasses, then 45% do not wear glasses. Of those members, 30% are in 10th grade, so the probability is 0.45 × 0.30 = 0.135, or 13.5%. Rounded to the nearest whole percent, that is 14%, choice A.
