Question

Find that probability that a point chosen at random in the figure lies in the green area.

Answer 1

101/131

Answer 2

how did you do that

Answer 3

First find the areas of the three rectangles formed in the figure. They have areas of 35, 30, and 66. The "green" rectangles have a combined area of 101, while the entire figure would have a total area of 131. Therefore the probability would simply be the ratio of the combined area of the green rectangles to the total area. This should yield 101/131.
