Question

in 80 spins, how many times would you expect to get blue?
pie chart with four equal sections: r (red), b (blue), g (green), y (yellow)
options: 15, 10, 30, 20

Explanation:

Step1: Find probability of blue

The spinner has 4 equal sections, so the probability of landing on blue is $\frac{1}{4}$.

Step2: Calculate expected number

Multiply total spins by probability: $80 \times \frac{1}{4} = 20$
