Question

A box of cookies has 25 chocolate, 15 vanilla, and 10 strawberry cookies. What is the probability, expressed as a percent, of randomly selecting a strawberry cookie?

A: 10%

B:15%

C:20%

D:33%

Answer 1

C.) 20%

Explanation:

First we must calculate our total number of cookies:

25+15+10=50

This will be our denominator, our numerator in our fraction will be the amount of strawberry cookies (10):

`(10)/(50)=(1)/(5)  =0.20`

Now we multiply our result by 100 to convert from decimal to percentage and so:

0.20 x 100 = 20%
