If you roll a die 38 times and 12 of the rolls result in a "5," what empirical probability was observed for the event "5"?

    To quote one of our very good math and science tutors: “You will find here at Jiskha that long series of questions, posted with no evidence of effort or thought by the person posting, will not be answered. We will gladly respond to your future questions in which your thoughts are included.”

    The empirical probability, which is "what you measured by experiment" is 12/38 = 6/19, with 38 tosses.

    If you had rolled the die thousands of times, you should have approached a probability of 1/6, if the die was not "loaded".

    It is not unusual to get different empirical values tfrom the true probability, when there are relatively few samples.
