Question

probability and statistics
ryder shot a model rocket over an area that consists of two grassy areas,
which are shaded in the diagram, and an area with no grass, which is not
shaded.
what is the probability that his model rocket will land in a grassy area?
15 acres
30 acres
5 acres

Explanation:

Step1: Calculate total area

Total area = \(15 + 30+5=50\) acres.

Step2: Calculate grassy area

Grassy area = \(15 + 5 = 20\) acres.

Step3: Calculate probability

Probability \(P=\frac{\text{Grassy area}}{\text{Total area}}=\frac{20}{50}=0.4\)

Answer:

\(0.4\)
