Question

There is a spinner with 13 equal areas numbered one through 13 if the spinner is spun one time what is the probability that the result is a multiple four or multiple of 3

Answer 1

Answer: 6/13 or 46%.

Answer 2

The probability that the result is a multiple of 3 and a multiple of 4 is
`(1)/(13)`

Explanation:

The spinner is numbered from 1 to 13.

When the spinner is spun once, the possible outcomes are

{1,2,3,4,5,6,7,8,9,10,11,12,13}

Desired outcome is a multiple of 3 and a multiple of 4. So, the number should be divisible by 3 as well as 4.

List of multiples under the possible outcomes:

3= 3,6,9,12

4=4,8,12
