If the spinner is spun one time then the probability that the result is a multiple of 5 and a multiple of 3 is 8/15.
Given that the spinner is numbered from 1 to 15.
We are required to find the probability that the result is a multiple of 5 and a multiple of 3.
Probability is likeliness of happening an event among all the events possible. It lies between 0 and 1.
Probability=Number of items/Total of items.
Multiple of 5 from 1 to 15=5,10,15
Multiple of 3 from 1 to 15=3,6,9,12,15
Probability that the result is the multiple of 5=3/15
Probability that the result is the multiple of 3=5/15
Probability that the result is multiple of 5 and 3=3/15+5/15
=8/15
Hence if the spinner is spun one time then the probability that the result is a multiple of 5 and a multiple of 3 is 8/15.
