Q:
# In a certain class of students, there are 9 boys from wilmette, 3 girls from kenilworth, 7 girls from wilmette, 6 boys from glencoe, 4 boys from kenilworth and 5 girls from glencoe. if the teacher calls upon a student to answer a question, what is the probability that the student will be from kenilworth? round your answer to three decimal places.

Accepted Solution

A:

Total Kenilworth students = 4 boys + 3 girls = 7.

Total students = 9+3+7+6+4+5=34.

So, the probability of a student from Kenilworth being called upon is 7/34=0.20588, or 20.588%

Total students = 9+3+7+6+4+5=34.

So, the probability of a student from Kenilworth being called upon is 7/34=0.20588, or 20.588%
