Question

Suppose you have a box with 3 blue marbles, 2 red marbles, and 4 yellow marbles. You are going to pull out one marble, record its color, put it back in the box and draw another marble. What is the probability of pulling out a red marble followed by a blue marble? Be sure to reduce your answers.

Answer 1

5/9 because you have to add those two together and put that number over the total number of marbles.
