Question

There is a spinner with 10 equal areas, numbered 1 through 10. If the spinner

is spun one time, what is the probability that the result is a multiple of 2 and a
multiple of 5?

Answer 1

10%

Explanation:

The multiples of 2 are 2,4,6,8,10, and so on

The multiples of 5 are 5, 10, 15, 20 , 25, and so on

It is evident that the only one that matches up between 1-10 is 10.

There are 10 options, and our chances are random. There is only 1 option for it to be a multiple of both 2 and 5. Therefore, the probability is 1/10, or 10%
