So of all the possibilities, the ones that meet our constraint of being a multiple of five, there are one, two, three, four, five, six, seven possibilities. So seven meet our constraint. So in this example, the probability of selecting a number that is a multiple of five is 7 twelfths. Let's do another one. The circumference of a circle is 36 pi. Let's draw this circle. The circumference of a circle is 36 pi.
