A bag contains 2 red, 5 blue, and 3 green balls. A ball is chosen at random. The probability of choosing a red ball is 1/5. What is the probability of not choosing a red ball?

4/5

Step-by-step explanation:

Since the total of all the balls are 2 + 5 + 3 = 10

The probability of choosing not a red ball is (5 + 3)/10 which is 8/10 or 4/5

The easier way is to go like this:  1 - 1/5 = 4/5

 4/5

4/5

Step-by-step explanation:

If the probability of choosing a red ball is 1/5, then the probability of this not happening is 1 - 1/5, or 4/5.
