Statistics Filter: Help me determine whether I can predict B from A.

Teach me - like you would a second-grader - enough about statistics, correlation, and/or regression analysis to solve a specific problem.

Assume I have two parameters for approximately 5.5 million entities: (A) a score (from 0 to 1000) and (B) a boolean that indicates something else about that entity that may or may not be related.
How do I determine whether or not there's any statistical relationship between (A) and (B)? That is, I'd like to know whether it's feasible to infer (B) from (A), and if so, how strongly (ideally via a single metric) I might be able to do so.
What (public-domain) tools out there might be able to help me determine the answer to this question? (If it helps, (A) and (B) are fields in a mysql database.)
