Answer

Answer:

A. 14%

Explanation:

Step1: Find the percentage of non - glass - wearers

If 55% of the team members wear glasses, then the percentage of team members who do not wear glasses is $100%-55% = 45%$.

Step2: Calculate the desired probability

We know that 30% of the non - glass - wearers are in the 10th grade. So the probability that a randomly chosen member does not wear glasses and is in the 10th grade is $0.45\times0.30= 0.135$.

Step3: Convert to percentage and round

Converting 0.135 to a percentage gives 13.5%. Rounding 13.5% to the nearest whole percent gives 14%.
