A spinner with 10 equally sized slices is shown below. (2 slices are black, 4 are grey, and 4 are white.) The dial is spun and stops on a slice at random. What is the probability that the dial stops on a black slice? in simplest form

It has a 1 in 5 spins to land on a black slice because 2 out of the 10 are black so it is a 2 in 10 spins chance or 1 in 5 chance.
