Question

Find the indicated probability. A spinner has equal regions numbered 1 through 15. What is the probability that the spinner will stop on an even number or a multiple of 3?.

The numbers which are either a multple of a 3 or an even number (or both) are: 2, 3, 4, 6, 8, 9, 10, 12, 14, 15

There are 10 numbers in total which satisfy the conditions.

There are 15 total possiblities which could occur.

Therefore, the probablity is 10/15 which can be reduced to 2/3
