A spinner with 6 equally sized slices has 3 red slices, 1 yellow slice, and 2 blue slices. The dial is spun and stops on a slice at random. What is the probability that the dial stops on a red slice?
Write your answer as a fraction in simplest form.
There are a total of 6 slices on the spinner. Since 3 of them are red, the probability that the dial stops on a red slice is 3/6. This fraction simplifies to 1/2.
Therefore, the probability is 1/2.
