The town planning department surveyed some residents of a town about home ownership. The tables show the results of the survey.

At address's At address Total for category
Lessthan 2 years. More than 2years
.Owners 2000. 8000. 1000
.Renters 4500. 1500. 60000
Total 6500. 9500. 16000

DETERMINE THE FOLLOWING POSSIBILITIES

A) p(residents homes)
B) p(residents rents and has lived at present address less than two years)
C) P(home owner has lived at present address more than two years)
 
2000 + 8000 does not equal 1000. Did you mean 10000, or is there some other mistake?

4500 + 1500 does not equal 60000.

It is going to be difficult to help you if we cannot have confidence in your numbers.

I am a bit confused as I do not see any of your work. It is extremely hard to help you if we do not see your work. Maybe you made a simple mistake which we can point out or we get to see how you want to solve it and we can give you guidance.
 
As jomo indicates, we like to see work so we can see exactly what is giving you trouble.

Here we have the initial problems that you have not given us the question exactly and the question itself may be badly worded.

In the strictest sense, what you have given us is not a question about probability at all.

Let's consider the first question, which may be about the "probability" that a resident will own his or her dwelling place.

So let me ask a different question. Based on the numbers given, what percentage of the population own their dwelling places? How did you calculate that percentage?

Now if we asked a resident "at random," which means that each resident has an equal probability of being asked, whether that individual owns or rents, what is the probability that the answer will be "own."
