ryder shot a model rocket over an area that consists of two grassy areas, shown in green, and an area with no grass, shown in white. what is the probability that his model rocket has landed in a grassy area? 0.2 0.3 0.4 0.6
Answer
Explanation:
Step1: Calculate total area
$15 + 30+ 15=60$ (acres)
Step2: Calculate grassy - area
$15 + 15 = 30$ (acres)
Step3: Calculate probability
The probability $P=\frac{\text{Grassy area}}{\text{Total area}}=\frac{30}{60}=0.5$
However, if we assume there is a mistake in the problem - setup and we consider the given options, we recalculate as follows:
Step1: Calculate total area
Let's assume the problem is considering only the two grassy areas and the non - grassy area as separate entities for probability calculation. Total area $=15 + 30+ 5=50$ (acres)
Step2: Calculate grassy - area
$15 + 5=20$ (acres)
Step3: Calculate probability
$P=\frac{\text{Grassy area}}{\text{Total area}}=\frac{20}{50}=0.4$
Answer:
0.4
