There is a spinner with 15 equal areas, numbered 1 through 15. If the spinner is spun one time, what is the probability that the result is a multiple of 5 and a multiple of 3?

Respuesta :

Answer:

6.67%

Step-by-step explanation:

Find the amount of numbers that are multiples of 3 and 5

multiples of 3 = 3, 6, 9, 12, 15

multiples of 5 = 5, 10, 15

only 15 overlaps between these two groups, so it is one number

the total number of available numbers is 15

1/15 = 0.0667

multiply this by 100 to get a percentage

0.0667 * 100 = 6.67%
