Question

The random variable x represents the number of cars per house hold in a town of 1000 households, find the probability of randomly selecting a household that has at least one car

0 1 2 3 4 cars
125 428 256 108 83 houses

Answer 1

To find the probability of randomly selecting a household that has at least one car, calculate the probability of no cars and subtract it from 1.

Step-by-step explanation:

The random variable X represents the number of cars per household in a town of 1000 households. To find the probability of randomly selecting a household that has at least one car, we need to calculate the probability of no cars and subtract it from 1.

The probability of randomly selecting a household with 0 cars is:
P(X = 0) = 125/1000 = 0.125

Therefore, the probability of randomly selecting a household with at least one car is:
P(X >= 1) = 1 - P(X = 0) = 1 - 0.125 = 0.875

ill guess 2 or 3 not sure though
