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