A t-shirt company sells shirts in 4 different sizes (Small, Medium , Large and XtraLarge) that are
available in blue, red, white, black or gray. If a shirt is selected at random
how many different outcomes are there?

The total number of combinations available to just pick 1 t-shirt is 20

Explanation:

Given:

4 different sizes of t-shirts are available

5 different colors of t-shirt are available

Different outcomes if the t-shirts have to be picked one by one:

Different outcomes = 4! + 5!

                                = 24 + 120

                                = 144

Number of combinations available to just pick 1 t-shirt is:

Number of combinations = 4 X 5

                                          = 20

Therefore, the total number of combinations available to just pick 1 t-shirt is 20
