What is probability ?

"Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one. Probability has been introduced in Math to predict how likely events are to happen. The meaning of probability is basically the extent to which something is likely to happen. This is the basic probability theory, which is also used in the probability distribution, where you will learn the possibility of outcomes for a random experiment."

Given,

There are 1000 households and there are 125 + 428 = 553 households with 1 or no cars.

Therefore,

The probability of selecting a household with less than 2 cars is [tex]553/1000 = 0.553[/tex]

Hence, the probability of randomly selecting a household that has at least one car = 0.553.
