A Jar contains 4 white chips, 5 purple chips, and 1 black chip. Chips are selected randomly one at a time, and are not replaced
P(white, then purple, then black)

1 / 36

Step-by-step explanation:

There are 4 + 5 + 1 = 10 chips so there are 10 * 9 * 8 = 720 ways to choose 3 chips and not replace them. There are 4 ways to choose the white chip, 5 ways to choose the purple chip and 1 way to choose the black chip so there are 4 * 5 * 1 = 20 successful ways, therefore, the probability is 20 / 720 = 1 / 36.
