A box contains 10 chips. The chips are numbered 1 through 10. Otherwise, the chips are identical. From this box, we draw one chip at random, and record its value. We then put the chip back in the box. We repeat this process two more times, making three draws in all from this box.
How many elements are in the sample space of this experiment?
What is the probability that the three numbers drawn are all multiples of 3?
