Question

A game has a spinner with 15 equal sectors labeled 1 through 15. what is p(multiple of 3 or multiple of 7)? 215 13 25 715

Answer 1

Answer: D. 7/15 or

Explanation:

You have 15 possible outcomes

Probability= possibilities/outcomes

Possible numbers that are multiples of 3 are: 3, 6, 9, 12, 15. There are 5 possibilities.

P(multiple of 3) = 5/15

Possible numbers that are multiples of 7 are: 7, 14, . There are 2 possibilities.

P(7) = 2/15

Because of the or you add th e probabilities

P(multiple of 3 or multiple of 7) = 5/15 +2/15 =7/15
