Answer 1

This question is a conditional probability question

P(B|A) means Event B given Event A

In other words, event A has already happened, now what is the chance of event B?

From the given question

let

B = the event that a resident is married.

A = the event that the person owns their home.

So

Thus

$P(B\text{/A)=}\frac{80}{320}=\frac{1}{4}$
