A spinner is spun that has 15 equal-sized sections numbered 1 to 15. What are the odds the spinner lands on an odd number?

Question

The answers are:

A. 8:7

B. 7:8

C. 6:9

D. 8:15

Answer 1

There are 8 odd numbers: 1, 3, 5, 7, 9, 11, 13, and 15

There are 7 even numbers: 2, 4, 6, 8, 10, 12, and 14

The odds of being an odd number are the number of successes (getting an odd) divided by the number of failures (not getting an odd or, in other words, getting an even) so 8:7
