Changed location to: Word Problems: Problems on percentages, ratios, and fractions.

Here you must use the Law of And.

Since this is such a basic problem, I would recommend reading the law of Or and the law of And on Math bench. Use this search query since I cannot add a link.

Since Mr. Escobar got a green car AND a gray car, we multiply, using the Law of And.

Givens:
- 12 white cars
- 8 grey cars
- 6 red cars
- 3 green cars

We now know there are 29 total cars

Thus
{{{(3/29)*(8/29)}}}
Multiply fractions
{{{24/841}}}
The probability that Mr. Escobar gets a green car and then a gray car is {{{24/841}}}.
