Question

A spinner with

9
equally sized slices is shown below. The dial is spun and stops on a slice at random. What are the odds in favor of landing on a white slice?
note their are 7 white and 2 black

Answer 1

If a spinner has 9 equally-sized slices, then there is an equal chance of the spinner landing on any one of those slides. If, as in this case, there are 7 white slices and 2 black slices, then the chance of the spinner landing on a black slice is 2/9. And, to answer the question, the odds of landing on a white slice are therefore 7/9, or about 78%.
