Question

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

Explanation:

Step1: Calcular área total

$15 + 30+5=50$ acres

Step2: Calcular área de hierba

$15 + 5 = 20$ acres

Step3: Calcular probabilidad

La probabilidad $P$ que el cohete aterrice en un área de hierba se calcula como el área de hierba dividida por el área total. $P=\frac{20}{50}=0.4$

Answer:

D. 0.6
