Question

the random variable x represents the number of cars per household in a town of 1000 households.
find the probability of randomly selecting a household that has between one and three cars,
inclusive.
cars households
0 125
1 428
2 256
3 108
4 83
a. 0.792
b. 0.208
c. 0.256
d. 0.125

Explanation:

Step1: Calculate total number of households

Total households = \(125 + 428+256 + 108+83=1000\)

Step2: Calculate number of households with 1 - 3 cars

Number of households with 1 - 3 cars=\(428 + 256+108 = 792\)

Step3: Calculate probability

Probability \(P=\frac{792}{1000}=0.792\)

Answer:

A. \(0.792\)
