#### Answer

P(not green)=$\frac{3}{4}$

#### Work Step by Step

Orange section=2
Blue section=1
Green section=1
Total section=4
P(event)=$\frac{numberoffavorableoutcomes}{numberofpossibleoutcomes}$
The number of possible outcomes is 4 because that is the total number of sections. 3 out of 4 sections are not green so 3 is the number of favorable outcomes.
P(not green)=$\frac{3}{4}$
