Answer
P(orange)=$\frac{1}{2}$
Work Step by Step
Orange section=2
Blue section=1
Green section=1
Total sections=4
P(event)=$\frac{numberoffavorableoutcomes}{numberofpossibleoutcomes}$
The number of possible outcomes is 4 because that is the total number of sections. 2 sections are orange so that is the number of favorable outcomes.
P(orange)=$\frac{2}{4}$ -simplify-
P(orange)=$\frac{1}{2}$
