Question

he plans to spin it 80 times. which equation predicts the number of times that he could spin green?
○ $p(\text{green}) = \frac{1}{8}(80)$
○ $p(\text{green}) = \frac{2}{8}(80)$
○ $p(\text{green}) = \frac{3}{8}(80)$
○ $p(\text{green}) = \frac{1}{2}(80)$

Explanation:

Step1: Count total sections

Total sections = 8

Step2: Count green sections

Green sections = 2

Step3: Find probability of green

Probability $P(\text{green}) = \frac{\text{Green sections}}{\text{Total sections}} = \frac{2}{8}$

Step4: Predict total green spins

Multiply probability by total spins: $\frac{2}{8}(80)$

Answer:

$\text{P(green)} = \frac{2}{8}(80)$
