Question: For Problems 9-11, refer to the information below.

A small real estate company that specializes in residential listings recently became interested in determining the likelihood of one of their listings being sold within a certain number of days. An analysis of the company sales of 800 homes in previous years produced the following data.

Days Listed Until Sold

Initial Asking Price Under 30 31-90 Over 90 Total

Under $150,000 50 40 0 90

$150,000-$199,999 25 150 80 255

$200,000-$250,000 15 270 110 395

Over $250,000 10 30 20 60

Total 100 490 210 800

If a listing is randomly selected, what is the probability that it was listed for under 30 days until sold?
