Question

A spinner has 3 red spaces, 5 white spaces, and 1 black space. If the spinner is
spun once, what is the theoretical probability of the spinner NOT stopping on
red?
P(Not red) =

Answer 1

Answer:

$\frac{2}{3}$

Step-by-step explanation:

If we have 3 red spaces, 5 white spaces, and one blank space, there are a total of 9 spaces.

Since there are 3 red spaces, there is a $\frac{3}{9} = \frac{1}{3}$ chance of getting a red. However, the question asks the probability of not getting a red, so the chances of not getting a red are $1 -\frac{1}{3} = \frac{2}{3}$.

Hope this helped!
