Question

Jason has a marble jar that contains 9 orange marbles, and 10 purple marbles. He will draw two marbles from the jar one at a time without replacing the first marble.

What is the probability that Jason gets an orange marble on his first draw and a purple marble on his second draw?

Answer 1

Answer: 5/19

Explanation:

9 orange + 10 purple = 19 total

First draw - get orange:

9/19

Second draw - get purple - without replacing:

10/18

Math:

9/19*10/18 = 5/19 (I hope it’s okay for it to be a fraction)
