Question

12 balls numbered 1 through 12 are placed in a bin. Joe produces a list of three numbers by performing the following sequence three times: he chooses a ball, records the number, and places the ball back in the bin. How many different lists are possible?

Accepted Answer

There are 12 options for each ball to be drawn, so there are a total of 12^3 = 1728 possible drawings.
