Asked by Dallas
I need some help with the set up please.
Joella has a bag of marbles. The bag contains 10 red marbles, 5 green marbles, and 3 blue marbles. She will randomly select 2 marbles from the bag one at a time without replacement. What is the probability that Joella will select a red marble first and then a blue marble?
I got 10/18*3/16, but when I solve it, the answer is not one of the multiple choice answers. Thank you.
