Welcome. What have you done towards the solution?

This question is quite standard for probability. One suggestion is to use tree diagram to solve. I believe we all learn this from school. Give it a try.

First thing you need to specify whether P(red, red, blue) means "red marble first then red marble second then blue marble third" or "two red marbles and one blue marble in any order".
