Probability? i forget what this is called its simple

  1. Aug 13, 2014 #1
    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.

    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?
