Question

1. the spinner below is divided into eight equal regions and is spun once. what is the probability of not getting red? red green yellow red blue red purple white

Explanation:

Step1: Count red regions

There are 3 red - colored regions out of 8 equal regions on the spinner.

Step2: Calculate probability of getting red

The probability of getting red, $P(\text{red})=\frac{3}{8}$.

Step3: Calculate probability of not getting red

The probability of not getting red is $P(\text{not red}) = 1 - P(\text{red})$. Substitute $P(\text{red})=\frac{3}{8}$ into the formula: $P(\text{not red})=1-\frac{3}{8}=\frac{8 - 3}{8}=\frac{5}{8}$.

Answer:

$\frac{5}{8}$
