There is a spinner with 13 equal areas, mumbered 1 through 13. If the spinner is spun one time, what is the probability that the result is a multiple of 3 and a multiple of 4

The numbers that are multiples of 3 and multiples of 4 between 1 and 13 are 12. These numbers are 0, 12.

Therefore, the probability of spinning a multiple of 3 and a multiple of 4 is 2/13.
