Question

A store manager selects 50 cases of soda and finds 2 cans that have dents. If the store had 75 cases, how many cans can she expect to have dents in them?

Answer 1

3

Explanation:

because 2 dents in 50 the probability is 1 dent in 25 cans so 25×3 = 75 and 1×3 =3 so 3 dents in 75 cans its simple

Answer 2

3 dented cans

Explanation:

So out of 50 cases, there were 2 dented cans. That averages to 1 dented can for every 25 cases. (1/25)

So for 75 cases, we could multiply:

75 x (1/25) = 3. The manager could expect to find 3 dented cans.

(Another way to look at this: For 75 cases, think of it as 3 groups of 25 cases. For each group of 25 cases, expect 1 dented can. So for 3 groups, 3 dented cans.)
