Answer 1

5/9

Explanation:

The spinner is divided into 3 equal parts numbered 1 through 3.

ONE SPINNER:

• 1 = 1/3
• 2 = 1/3
• 3 = 1/3

Gina plays a game that involves spinning spinner twice.

Each combination has an equal probability. 1/3 * 1/3 = 1/9. Each combination has the probability of 1/9.

SEE ATTACHMENT.

You only need the combinations which contain at least one 1. There are 5 combinations which contain at least one 1. 5 * 1/9 = 5/9
