The probability of spinning three times before getting red is 0.6084.
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.
