Did you forget to put a picture I can’t see the question
The probability of spinning three times before getting red is 0.6084.
<h3>What is probability?</h3>
This is the term that is used in mathematics to show the likelihood of something happening.
We first solve for the probability of not getting red
P(not Red) = P(Blue) + P(Green) = 0.63+0.15 = 0.78
P(not Red) × P(not Red) = 0.78 × 0.78 = 0.6084
The probability of spinning at least three times will be 60.84 percent.

Explanation:
According to a study conducted by an organization, the proportion of Americans who were afraid to fly in 2006 was 0.10. A random sample of 1,100 Americans results in 121 indicating that they are afraid to fly. Explain why this is not necessarily evidence that the proportion of Americans who are afraid to fly has increased Click here to view the standard normal distribution table (page 1). Click here to view the standard normal distribution table (page 2). Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. This is not necessarily evidence that the proportion of Americans who are afraid to fly has increased above 0.10 because the sample proportion, is very close to 0.10 (Type an integer or a decimal.) OB. This is not necessarily evidence that the proportion of Americans who are afraid to fly has increased above 0.10 because the probability of obtaining a value equal to or more extreme than the sample proportion is which is not unusual. (Round to four decimal places as needed.) OC. This is not necessarily evidence that the proportion of Americans who are afraid to fly has increased above 0.10 because the value of np(1-P) is less than 10 OD. This is not necessarily evidence that the proportion of Americans who are afraid to fly has increased above 0.10 because the sample size n is more than 5% of the population.
