Question

14) Samantha ran to the store to pick up some candy. The store had 12 aisles. Ashley randomly picked an aisle to

start looking for cereal. What is the probability that she chose an aisle that is a factor of 24?


Total possible outcomes:


# of factors of 24:


P (Factor of 24)

Answer 1

58.33% probability that she chose an aisle that is a factor of 24

Explanation:

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

In this question:

12 values, from 1 to 12.

Of those:

1,2,3,4,6,8 and 12 are factors of 24. That is, the division of 24 by these values leaves no remainder.

So

There are7 values which are factors of 24.

7/12 = 0.5833

58.33% probability that she chose an aisle that is a factor of 24
