In a parking lot there are only white cars, green cars, and red cars. If one car is selected at random from

the lot, the probability that the selected car would be a green car is 1/6, and the probability that it would
be a red car is 1/8. What is the probability that it would be a white car?

What you would do is find a common denominator of 48
Then cross multiple and you would add up to get 14/48 them simplify it
7/24

Answer:

17/24 chance for white car

Explanation:

We know that there is a 1/6 chance that it will be green and 1/8 that it will be red so whatever's left has to be white. We can just add the fractions that we have and subtract them from one to get the probability of getting a white car.

1/6+1/8=?

Find the lowest common denominator (24)

4/24+3/24=7/24

Subtract it from 1

24/24-7/24=17/24

17/24 chance that it's white
