Question

Kendra has a bowl containing 10 blue marbles, 15 yellow marbles, 5 green marbles, and 6 red marbles of the same size. She will randomly pull out a marble, keep it outside the bowl, and then pull out another marble. What is the probability she will draw a red marble and then a yellow marble?

1/8

5/72

1/14

3/20

Answer 1

You have 36 marbles total. The equation you use to solve this problem is 6/36 x 15/35. The reason why it's 15/35 and not 15/36 is because of the first marble you took out. So multiply 6/36 by 15/35 and that's your answer! :)
Make sense?
