@Phira: I was a 4k user there (the 6th user or so, as the site is on beta and quite new) but deleted my account due to some unexpected events.

It might be more helpful to explain more details instead of only the definitions.

comment Find $p(B)$ given $P(A)$, $P(A\cup B)$, and one more piece of information
@mastergoo: 1) $1/3=1/4+p$ , 2) $1/3=1/4+p+p/4$ , 3) ... _ The main formula is $P(A \cup B)=P(A)+p(B)−P(A \cap B)$ and you substitute $P(A \cap B)$ with what I said in each part!

I suspect the other one was wrong as well, you need to be more careful.
