Answer:
0.17
Step-by-step explanation:
First, we can easily calculate that the area of the rectangle is 7 * 5 = 35
Next, to find the probability of choosing a point in the triangle, we need to find the area of the triangle compared to the area of the rectangle. Notice that the square has nothing to do with the solution because we are only interested in finding the probability for the triangle!
Since the area of the triangle is base * height / 2 or 4 * 3/2 = 6, the probability is 6/35. Plugging this value in the calculator gives us 0.17
