$P(yellow)=\frac{1}{4}$

#### Work Step by Step

We are given that the probability of an event is equal to the number of ways that the event can occur divided by the number of possible outcomes. The spinner is divided into 8 parts, so there are 8 possible outcomes. The spinner has 2 yellow sections. Therefore, $P(yellow)=\frac{2}{8}=\frac{1}{4}$
