Anna is throwing a fair die with twelve faces.

What is the probability that the number of dots on the top face of the die is a multiple of 12?

Answer: 1/12.

Step-by-step explanation: If the fair die has 12 faces that means the numbers on the die are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12. Among these, the only multiple of 12 is 12 itself. 12*1 = 12, so 12 is a multiple of 12. Thus, the probability that the number of dots on the top face of the die is a multiple of 12 is 1 out of 12.
