Question

A bag contains 10 blue, 6 green, and 4 red marbles. You choose a marble with one hand and then a second marble with the other hand. What is the probability that you will first choose a red marble followed by a green marble?

Answer 1

I would say 6/98.

Hope this helped!

Answer 2

The bag contains 10+6+4=20 marbles, so the probability of selecting a red then a green in that order without replacement is:

(4/20)(6/19)=24/380

6/95  (≈6.32%)
