In a certain class of students, there are 11 boys from wilmette, 7 girls from wilmette, 5 boys from winnetka, 4 girls from winnetka, 4 boys from glencoe, and 4 girls from glencoe. if the teacher calls upon a student to answer a question, what is the probability that the student will be a boy? round to three decimal places as needed.

.571

Step-by-step explanation:

We need to find the total number of boys

11+5+4 = 20

And the total number of students

11+7+5+4+4+4 = 35

The Probability that the student is a boy is boy/total

P (boy) = boy/total

           = 20/35

           =4/7

            =.571428571

  to 3 decimal places

           =.571
