Question

A spinner with 10 equally sized slices is shown below. (2 slices are red, 4 are blue, and 4 are yellow.) The dial is spun and stops on a slice at random. What is the probability that the dial stops on a slice that is not red?Write your answer as a fraction or a whole number.

Answer 1

We will have the following:

Since there are 8 slices that are not red, the probability will be given by:

`p=(8)/(10)\Rightarrow p=(4)/(5)\Rightarrow p=0.8`

So, the probability will be of 4/5, that is 80%.
