Answer

Explanation:

Step1: Calculate forest area

The forest - shaded areas are 45 acres and 35 acres. So the total forest area is $45 + 35=80$ acres.

Step2: Calculate probability

The probability $P$ that the keys land in the forest is the ratio of the forest area to the total area. The total area is 100 acres. So $P=\frac{80}{100}=0.8$.

Answer:

0.8
