explain the difference between disjoint and overlapping events
I think this is more of a statistics question.
Disjoint events are two events that cannot happen simultaneously (i know this from ap stat).
Overlapping events (im speculating here) is probably the opposite, they either only happen together (if one occurs, the other must occur, and vice versa, if one doesn't occur, the other can't occur). This could also be considered a dependent event I guess (just like disjoint events are independent).
