fifty - five percent of the members of the junior varsity swim team wear glasses. 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?\n14%\n17%\n55%\n67%
Answer
Answer:
A. 14%
Explanation:
Step1: Find percentage of non - glasses wearers
The percentage of members who wear glasses is 55%. So the percentage of members who do not wear glasses is $100 - 55=45%$.
Step2: Calculate the desired probability
Of the non - glasses wearers, 30% 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: Round to the nearest whole percent
Rounding 0.135 to the nearest whole percent gives 14%.
