A polling organization is asking a sample of U.S. Adults how many pets they own. The frequency distribution below shows the results. Response Number of Times, f None 354 One 981 Two 352 Three 200 Four or more 113 What is the probability that the next person asked has two pets? Round to three decimal places if necessary.

Answer 1

The probability that the next person asked has two pets is 0.176

Explanation:

The given parameters are;

The frequency distribution of the number of pets owned is presented as follows;

Number of Times
`{}` Frequency
`{}`

None
`{}` 354

One
`{}` 981

Two
`{}` 352

Three
`{}` 200

Four
`{}` 113

The probability that the next person asked has two pets = Proportion of the sample that own two pets = 352/(354 + 981 + 352 + 200 + 113) = 0.176

Therefore, the probability that the next person asked has two pets = 0.176
