Total people in the cafeteria = 7 + 48 + 45 = 100

There are 45 boys.

The probability would be the number of boys over the total number of people:

45/100, which simplifies to 9/20

Answer:

P(boys) =9/20

Step-by-step explanation:

To find the probability, we first need to find the total

7 teachers +48 girls + 45 boys =100

P(boys) = boys/total

            = 45/100

           = 9/20
