Aspinner used for a game is divided into 3 sections: yellow, green, and orange. janie spins the spinner 20 times. the spinner lands on green 8 times. what is the experimental probability that the spinner does not land on green?

Step-by-step explanation:

Given : A spinner used for a game is divided into 3 sections: yellow, green, and orange.

Janie spins the spinner 20 times.

The spinner lands on green 8 times.

It means , the number of times it does not land on green section = 20-8=12

Then, the experimental probability that the spinner does NOT land on green :-

∴ Required probability =

a negative exponent is translated as follows:

so, we have
