Question

A spinner has 18 equal-sized sectors labeled 1 through 18. The spinner is spun once.

What is the probability that the spinner lands on an even number or a number greater than 10?

1/2 4/9 11/18 13/18

Answer 1

Answer: 13/18

Explanation:

First you add up the amount of even numbers and the amount of numbers greater than 10

2,4,6,8,10 make 5 then add 8 more for 11-18, leaving you with 13 then take 13 and divide it by the total (18) and you will get 0.72 or 13/18

Answer 2

2/9

Explanation:

12,14,16,18 are all greater than 10, which is 4/18 numbers, simplified as 2/9
