In a certain class of students, there are 8 boys from Wilmette, 4 girls from Winnetka, 10 girls from Wilmette, 5 boys from Glencoe, 3 boys from Winnetka and 7 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?

43.24% probability that the student will be a boy

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Desired outcomes:

Student being a boy.

8 boys from Wilmette

5 boys from Glencoe

3 boys from Winnetka

So

Total outcomes:

All students

Probability:

43.24% probability that the student will be a boy

Step-by-step explanation:

BOYS

GIRLS

Total Number of Boys n(B)= 8+5+3=16

Total Number of Girls, n(G)=4+10+7 =21

Total Number of students, n(S) =21+16 =37

If a student is called randomly to answer a question,

P(Student will be a boy)

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

300pi
