Answer #1

A person who is college graduate may or may not be homeless, so these two events A and B may be disjoint or may be joint as well.

As its more possible that some homeless persons are college graduates, So A and B is joint is more possible

But being homeless doesn't effect the person to be a college graduate. or being college graduate has nothing to do with whther the person is homeless or not.

So the two events are Independent.

Therefore, Option B " The events A and B are joint and independent. " is correct
