A small real estate company recently became interested in determining the likelihood of one of their listings being sold within a certain number of days. An analysisof company sales of 800 homes in previous years produced the following data. Use of Excel is optional.

a. If A is defined as the event that a home is listed for more than 90 days before being sold, estimate the probability of A.

b. If B is defined as the event that the initial asking price is under $150,000, estimate the probability of B.

c. What is the probability of A > B?

d. Are events A and B independent?
