Question

A box of cookies contains three chocolate chip cookies, two oatmeal raisins, and four

gingerbreads. What is the probability of picking a chocolate chip, and then a gingerbread?

Answer 1

Answer:
`(1)/(6)`

Explanation:

Given

A box contains 3 chocolate chip cookies, 2 oatmeal raisins, and 4 gingerbreads

First Probability of selecting a chocolate chip is

`\Rightarrow (3)/(9)`

After that there are 8 items left. So probability of selecting a gingerbread

`\Rightarrow (4)/(8)`

On combining, the required probability is

`\Rightarrow (3)/(9)* (4)/(8)\\\\\Rightarrow (1)/(6)`
