How many outcomes are there in the experiment in which you pick one color from the American Flag (RWB), then pick one letter from the list A, B,C, D,E, and then pick one number from the digits 0-9 (Note there are 10 digits here!)

150 possible different outcomes

Step-by-step explanation:

The number or colors from which we can choose is three, the number of letters five and the number of digits ten. And since we need to choose one each time. Is like finding the number of triples in the Cartesian set C x L x D, where C stands for colors, L for letters and D for digits, and all are finite sets. Then the number of elements in C x L x D is the product of the number of elements in each set, that is

|C x D x L|=|C|•|D|•|L|=3*5*10=150 different triplets or equivalently different outcomes.
