Quizplus · Accepted Answer

The probability that a homeowner has at least one pet is calculated by subtracting the number of homeowners with 0 pets from the total number of homeowners, then dividing by the total number of homeowners. This gives $\frac{33625 - 5617}{33625} = \frac{28008}{33625} \approx 0.833$.
