Answer:

a)14%

Step-by-step explanation:

Fifty-five percent of the members of the junior varsity swim team wear glasses.

So, 45% of the members of the junior varsity swim team do not wear glasses.

Of the team members who do not wear glasses, 30 percent of them are in the 10th grade.

The probability that a randomly chosen member of the JV swim team does not wear glasses and is in the 10th grade is:

[tex]\frac{30}{100}\times45[/tex]

= 13.5% rounded to 14%.
