Question

A spinner is divided into many sections of equal size. Some sections are red, some are blue, and the remaining are green. The probability of the arrow landing on a section colored red is 12 over 20. The probability of the arrow landing on a section colored blue is 6 over 20. What is the probability of the arrow landing on a green-colored section?

Answer 1

The probability is 2. There are 20 sections it can land on. So, 12/20 leaves 8 sections left. Blue takes 6 of those sections, so that leaves 2 sections left for green. So 2/20
