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 2 and a multiple of 5?
10 is the only multiple of 2 and 5, 1/15.
This answer is wrong the answer is Probability 9/15 or 3/5 or 0.6
To find the probability of the spinner landing on a multiple of 2 and a multiple of 5, we need to determine the number of favorable outcomes and the total number of possible outcomes.
First, let's determine the number of favorable outcomes. From 1 to 15, the multiples of 2 are 2, 4, 6, 8, 10, 12, and 14. The multiples of 5 are 5 and 10. Since 10 is a multiple of both 2 and 5, we have one favorable outcome.
Next, let's determine the total number of possible outcomes. Since the spinner has 15 equal areas, the total number of possible outcomes is 15.
Therefore, the probability of the spinner landing on a multiple of 2 and a multiple of 5 is the ratio of the favorable outcomes to the total outcomes:
Probability = Favorable Outcomes / Total Outcomes
= 1 / 15
= 1/15
So, the probability that the spinner will result in a multiple of 2 and a multiple of 5 is 1/15.
