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.
