Jerry randomly selects 20 boxes of crayons from the shelf
and finds 2 boxes with a least on broken crayon if the shelf holds 130 boxes
how many would you expect to have at least one broken crayon

You would expect 13 broken crayon boxes out of 130 boxes.

Step-by-step explanation:

It is given that,

Out of 20 boxes of crayons from the shelf Jerry finds 2 boxes of broken crayon.

Therefore, for 10 boxes of crayon from the shelf, he could find 1 broken box of crayon.

10 boxes = 1 broken box

To find the number of broken boxes out of 130 boxes :

Divide 130 by 10,

⇒ 130 ÷ 10

⇒ 13 broken boxes.

∴ You would expect 13 broken crayon boxes out of 130 boxes.
