SOLUTION: Seniors at a high school were asked what color car they drive. The results were put in a circle graph. The measure of each central angle is shown. If a senior is chosen at random

Algebra ->  Probability-and-statistics -> SOLUTION: Seniors at a high school were asked what color car they drive. The results were put in a circle graph. The measure of each central angle is shown. If a senior is chosen at random      Log On

Divide each by 360 degrees and that will be the probability
of the car color, P(W), P(R), P(B) and P(S)  

For this problem, you only need to find P(W) and P(B)

Then to find P(W or B), add P(W)+P(B)
