A vending machine has 5 colors (white, red, green, blue, and yellow) of gumballs and an equal chance of dispensing each.

A second machine has 4 different animal-shaped rubber bands (lion, elephant, horse, and alligator) and an equal chance of dispensing each.

If you buy one item from each machine, what is the probability of getting a yellow gumball and a lion band?

P ( yellow gumball and  lion band)  =  ( 1/5) (1/4)  = 1/20
