5-83.

A particular spinner only has two regions: green and purple. If the spinner is randomly spun twice, the probability of it landing on green twice is . What is the probability of the spinner landing on purple twice?

Find the probability of landing on green in one spin. Make a generic rectangle with the probabilities for Green and Purple at the top and left side. Then fill in the grid by multiplying the probabilities.

the probability of landing on green in one spin.
P(green and green)



The probabilities of all possible outcomes need to add up to or %. If is , what would be?

Use the value of to help you find the probability of landing on purple twice.
