Question

A spinner with 6 equally sized slices has (1 blue slice, 2 red slices, and 3 yellow slices). 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 blue?

Write your answer as a fraction in simplest form.

Answer 1

• B=1
• R=2
• Y=3

Sample space=S=6

Dials not blue=R+Y=2+3=5

so probability

`\\ \sf\longmapsto P(E)=(|E|)/(|S|)`

`\\ \sf\longmapsto P(E)=(5)/(6)`
