Question

Gary bought a gift for his friend and is having it gift wrapped at the store. The wrapping paper comes in four patterns: floral, spiral, cartoon character, and plain. For ribbon, he can choose between red, blue, or green. If Gary randomly selects a paper pattern and a ribbon color, what is the probability that he chooses spiral-patterned paper and a green ribbon?

Answer 1

Answer:
`\text{P(spiral-patterned paper and a green)}=(1)/(12)`

Explanation:

Given: The number of patterns in wrapping paper = 4

The number of colors available for ribbon = 3

Then, the total number of types of ribbons are in store =
`4*3=12`

Also, the number of type of ribbon has spiral-patterned paper and a green in color =1

So, if Gary randomly selects a paper pattern and a ribbon color, then the probability that he chooses spiral-patterned paper and a green ribbon is

`\text{P(spiral-patterned paper and a green)}=(1)/(12)`
