Two-Face falsely interprets "the law of averages", stating that it is the one true equalizer. In reality, "the law of averages" is the commonly held belief that over certain period of time a particular outcome of an event in a series of events will occur at a frequency that is similar to its probability. For example, if a person tosses a coin five times and all of the tosses lend on tails, one might wrongfully expect the next couple of tosses should lend on heads with more than 50% of probability.
