A spinner is divided into 8 equally sized regions. The regions are numbered with consecutive multiples of 10, beginning with 20. The spinner is spun 80 times.

How many spins are expected to show a multiple of 3?

1. Determine which numbers on the spinner are multiples of 3

2. Determine the probability of a spin showing a multiple of 3

3. Use the probability to find how many spins out of 80 will result in a multiple of 3
