Question

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

Answer 1

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.
