A spinner with 10 equally sized slices has 3 blue slices and 7 yellow slices. The dial is spun and stops on a slice at random. What is the probability that the dial stops on a red slice?

The answer is 0.

"The answer is 0." because there are no red slices

... only blue and yellow

To determine the probability of the dial stopping on a red slice, we need to gather some information. However, in the given scenario, the number of red slices on the spinner is not provided. Thus, without this critical information, it is not possible to calculate the probability.

If you have some additional information or if the number of red slices is provided, please let me know, and I'll be happy to assist you further.
