Lets say I have an event that happened 500 times in 2000 trials.
Then I want to say the event has 1 in 4 ... what? chance? probability? relative frequency? Its been years since I took a course on this stuff. I need the right words here. thanks

Yes, I would call it "relative frequency".

The classical statement would be that the relative frequency estimate of probability is 500/2000 or 1/4.
Or you could simply say that the event occurred in 25% of the trials you observed. What, exactly, are you looking to say?
