Patterns in Lottery Numbers

markmcb writes "Most everyone is familiar with the concept of the lottery, i.e., random numbers are selected and people guess what they will be for a cash prize. But how random are the numbers? Matt Vea has conducted a pattern analysis of the MegaMillions lottery, which recently offered a sum of $370M (USD) to the winner. Matt shows that the lottery isn't as random as it may seem and that there are 'better' choices than others to be made when selecting numbers. From the article, 'A single dollar in MegaMillions purchases a 1 in 175,711,536 chance of landing the jackpot ... a player stands a mildly better chance of winning a partial prize through the selection of weighted numbers.'" Includes some excellent charts of his analysis.

  1. Let's try some simulations shall we? by davidwr · · Score: 4, Informative

    Let's simulate the history of MegaMillions in a computer, using a hardware random-number-generator that we trust to be completely random with an even distribution.

    Examine the results and look for patterns. Odds are, you will see minor variations from "average." After all, if you flip a coin 1000 times, odds are you won't get exactly 500 heads and 500 tails.

    Next, let's repeat this 100 times. Odds are you will see such patterns in most of the experimental runs, but the patterns will vary from run to run.

    Think of the real-life MegaMillions lottery as a single experimental run.

    How do you counter this?

    You could slice-and-dice the MegaMillions into 100 "experimental runs" each consisting of a random 10% of actual drawings. While the overall trend of this slice-and-dice will reflect the real history of MegaMillions, the results of the individual "experimental runs" should vary enough to convince people that this is just a statistical fluke, or at least it's flukiness can't be ruled out.

    In particular, let's slice MM into 10 time periods with an equal number of drawings. Odds are the most recent time period's statistical anomalies won't match those of earlier times.

    The bottom line:

    There is nothing to suggest the statistical anomaly of the history of MM so far will continue.

  2. Re:Conclusions... by severoon · · Score: 4, Informative

    Can you win at roulette by betting there will be "only 8 reds in the next 13 spins"? No, you have to say *which* spins will be red of those 13. In other words, you're arguing here that order doesn't matter...but it clearly does.
