A spinner is divided into 5 equal regions. The sections are labeled 1, 2, 3, 4, and 5.

The probability of not spinning a 5 and flipping heads is

Answer 1

1/10

Explanation:

The probability of flipping heads is 1 out of 2 or 1/2

The probability of getting a 5 on the spinner is 1/5

The probability of getting both is 1/2 * 1/5 = 1/10
