Gina plays a game that involves spinning spinner twice. the spinner is divided into 3 equal parts numbered 1 through 3.what is the probability of spinning at least one 1

Step-by-step explanation:

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

ONE SPINNER:

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

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
