Question

A new shoe comes in three colors: tan, navy, or black. It also comes in full sizes 4 to 11. If a pair of shoes is chosen at random from a display of all the possible colors and sizes, what is the probability it will be a black size 9​

Answer 1

Three colors * 8 possible sizes = 24 different shoes

The probability that the shoe is going to be a size 9 black shoe is 1/24.
