We see, then, that the frequency distribution can tell us quite a lot about a random variable. For example, the data above shows that the most common number of aces to be dealt in a hand of five cards is 0 (this will occur about 66% of the time), and that being dealt all four aces will occur, on average, only about 2 times per 100,000 deals.
