Question

Leo will create a mural consisting of five

vertical stripes of different colors. If Leo has
eight different colors from which to choose,
and the order of the stripes matter, in how
many ways can he complete his mural?

Answer 1

he got 8 different colors to choose from for the first stripe. he has to choose from 7 for the second (one choose less bc he alrdy took one color)

that alone makes 56 different ways for just two stripes.

he will use 5 stripes in total, so the calculation is:

8*7*6*5*4 = 6720

(8!-3! would also work with the calculator 8! uses all the naturalnumbersfrom 1 to 8 and multiplies them)
