The problem states:
What is the probability of finding a home in the USA advertised on this website that is less than $100,000 or under 2000 square feet?
(At this point, we have a chart with data in it. The data is represented in thousands of dollars)
Chart
Prices------------------- Less than 2000 sq. Feet ----------------------2000 sq. ft or more ------------------totals
___________________________________________________________________________________________
less then 100 ----------------------13 -------------------------------------------- 3 ----------------------------------16
Between 100 and 300 -------------92 --------------------------------------------42 --------------------------------- 134
More than 300-----------------------5 --------------------------------------------45 ------------------------------------50
__________________________________________________________________________________________
Totals ----------------------------110 -------------------------------------------90----------------------------------200
Now, I found the first part!!
16/200=.08 or 8% probability of finding a home $100,000 or less.
(First part described)
16 is total of houses under $100,000/total number of houses 200
Second part
110/200=.55 or 55% probability of finding a home less then 2000 sq. feet
(2nd part described)
There are a total of 110 houses that are less then 2000 sq. feet. I took this number and divided by the total number of houses in the chart (200) and got my answer for this part.
THIS IS WHERE I NEED HELP!!!!!
Now that I have figured out the two answers independently of one another, I do not know how to write an answer or even go about finding the answer for the two sections combined. Again, the problem states
"What is probability of finding a home in the USA advertised on this website that is less than $100,000 or under 2000 sq. feet"?
Can you help??
