# Math Help - How to well if a data set is independent? if it's disjoint

1. ## How to well if a data set is independent? if it's disjoint

I have a table with age on the top and occupation specialty on the side and numbers in each cell. How do I tell if they are independent? If they are disjoint?

If $P(A\cap B)=P(A)P(B)$ then the events are independent.
