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. what is the probability that her keys have landed within the forest? 0.2 0.6 0.8 1.0 45 acres 20 acres 35 acres

Explanation:

Step1: Identify forest area

The forest - shaded area has 45 + 35 = 80 acres.

Step2: Calculate probability

The total area is 100 acres. Probability $P=\frac{\text{Forest area}}{\text{Total area}}=\frac{80}{100}=0.8$.

Answer:

0.8
