Question

a hang glider is soaring over a 100 - acre area that consists of thick forest and open fields. in the diagram below, the forested area is shaded in green and the open field is the white space. upon landing, the hang glider realizes she has dropped her keys.
45 acres
20 acres
35 acres
what is the probability that her keys have landed within the forest?
0.2
0.6
0.8
1.0

Explanation:

Step1: Calculate total forest area

The forested areas are 45 acres and 35 acres. So we add them: $45 + 35 = 80$ acres.

Step2: Calculate probability

Probability is the forest area divided by total area (100 acres). So $\frac{80}{100} = 0.8$.

Answer:

0.8
