Question

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 3 or a multiple of 4?

Answer 1

To find the probability of spinning a multiple of 3 or a multiple of 4 on the spinner, we determine the favorable outcomes (multiples of 3 or 4) and divide by the total number of possible outcomes. The probability is 8/15 or approximately 0.533 (rounded to three decimal places).

Step-by-step explanation:

To find the probability that the result of spinning the spinner is a multiple of 3 or a multiple of 4, we need to determine the number of favorable outcomes and divide it by the total number of possible outcomes.

The multiples of 3 from 1 to 15 are: 3, 6, 9, 12, and 15. The multiples of 4 from 1 to 15 are: 4, 8, and 12.

There are 8 favorable outcomes. The total number of possible outcomes is 15. Therefore, the probability is 8/15 or approximately 0.533 (rounded to three decimal places).
