Question

A bag contains 30 cookies: 9 vanilla, 9 chocolate, and 12 oatmeal. What is the probability that a chocolate is randomly selected?
A) .30
B) .33
C) .40
D) .60

Answer 1

There is 9 chocolate cookies, so the probability of choosing chocolate is $\frac{9}{30}$. We then simplify to get $\frac{3}{10}$, or 0.3.
