A bag contains 7 blue marbles, 3 red marbles, and 15 white marbles (and no other marbles). One marble is chosen without looking. What is P(white)?

Answer 1

Explanation:

P(white) is 3/5. So how we find it is first you find how much in total are in the bag. You add up 7 + 3 + 15 and get 25. That means there are 25 total outcomes. Since there are 15 white marbles, that means you have a 15/25 chance of picking a white marble. Simplify 15/25 and you get 3/5/
