Quizplus · Accepted Answer

The probability of a household having an annual income of $25,000 or more is the sum of the probabilities of the households having incomes in the ranges $25,000 - 34,999 and $45,000 or more. The probability of a household having an income in the range $25,000 - 34,999 is 28/100 = 0.28, and the probability of a household having an income of $45,000 or more is 10/100 = 0.1. Therefore, the probability of a household having an annual income of $25,000 or more is 0.28 + 0.1 = 0.38.
