Question

Of the 30 cars in a parking lot, 12 are blue, 8 are red, 6 are white, and 4 are silver. In simplest form, what are the odds in favor of a red or white car leaving first?

Answer 1

`p(red or white)=14/30=7/15`

Explanation:

`p(red or white)=p(red)+p(white)=8/30+6/30=14/30=7/15`

This is comparable to 30 marbles in a container where one has to get 1 marble. What is the probability that one will get a red or a white marble? p(red or white)`=(8+6)/30=7/15`
