Question

Spinner Experiment
Color Red Green Blue
Spins 5 8 7 What is the probability of spinning red? (Express you answer as a percent.)

What is the probability of spinning green? (Express you answer as a percent.)

Answer 1

Red spinned 5 times, Green spinned 8 times, and Blue spinned 7 times?

Answer 2

yeah

Answer 3

Alright. So if you want to find this, you want to figure out what's the possible outcomes. The possible outcomes goes to the denominator.
Do you know what's the possible outcomes?

Answer 4

no i don't

Answer 5

To find the possible outcomes, you want to find out how many time you spinned. So how many time did you spinned in that experiment?

Answer 6

20?

Answer 7

Good job. So the possible outcome is 20, since you only spinned 20 times.

Answer 8

Now how many time did you spinned red?

Answer 9

5

Answer 10

Good job. So the probability of spinning red in fraction form is 5/20. Does that make sense?

Answer 11

yeah
so spinning green would be 8/20?

Answer 12

Yes. Good job!
But those are in fraction forms, not in percent forms. ;)
Do you know how to convert it into percent?

Answer 13

yeah i think do i 5 divided by 20 x 100 correct?

Answer 14

Yes. And put the percent sign. :)

Answer 15

alright! thanks for the help!!

Answer 16

No problem! I hope this help. :)
