Question

what is the probability of spinning blue or green?
1/8
3/8
1/2
5/8

Explanation:

Step1: Count total sections

The spinner is divided into 8 equal - sized sections. So the total number of possible outcomes is $n = 8$.

Step2: Count favorable sections

There is 1 blue section and 2 green sections. So the number of favorable outcomes (blue or green) is $m=1 + 2=3$.

Step3: Calculate probability

The probability $P$ of an event is given by the formula $P=\frac{m}{n}$. Substituting $m = 3$ and $n = 8$, we get $P=\frac{3}{8}$.

Answer:

$\frac{3}{8}$
