Question

A bag contains five red marbles, four blue marbles, and three yellow marbles. You randomly pick a marble. What is the probability the marble is red or blue?

Answer 1

Answer and Step-by-step explanation:

First, find the total amount of marbles.

5 + 4 + 3 = 12

There are 12 marbles in total.

The probability of picking a red or blue marble would be 9 out of 12, since it is asking for either the red marble or the blue marble.

9/12 is the answer. (Simplifies down to 3/4)
