A bag has 3 red marbles, 2 purple marbles, and 5 orange marbles. Jamal picks two marbles at random.

What is the Probability of him choosing (orange, then purple) without replacing the first marble he picked?

P.S: I know the answer is 1/9, but I don't know how to do the work

10 marbles in all, so
P(orange, purple) = 5/10 * 2/9 = 1/9
