Question

in 100 spins, how many times would you expect to get yellow?
options: 20, 25, 30, 35 (with a spinner divided into yellow (y), red (r), green (g), red (r), blue (b) sections)

Explanation:

Step1: Count total equal sections

The spinner has 5 equal sections.

Step2: Find yellow section count

Yellow (Y) is 1 section.

Step3: Calculate probability of yellow

Probability $P(Y) = \frac{1}{5}$

Step4: Compute expected number

Expected value = $100 \times \frac{1}{5} = 20$

Answer:

20
