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

80% (I'm pretty sure)

There are 10 balls in total.

5 + 3 + 2 = 10

2/10. 5/10. 3/10.

20%. 50%. 30%

20% of the red ball getting chosen so

100 - 20 = 80% of it not getting chosen
