Michigan Keno Stats Over 16 Years
After hearing a statistics professor told his class that some numbers in Keno have better odds than others, I wanted to check his claim. So, I went to the Michigan Lottery website and wrote a script to take all 16 years worth of Keno winning numbers. That's 83072 numbers drawn 22 at a time for a total of 3776 rounds of Keno.
I found that the best number to pick is a tie between 05 and 11. Each one appears 28.9989407% of the time. The worst number to pick is 29, as it appears only 24.7351695% of the time.
But does this actually matter? Maybe a little but not much. If you look at the difference, 05 was picked 161 more times than 29. There were 83072 drawn. 161 extra times isn't that bad. The standard deviation of all percents was 0.78.
So, was the professor right? Technically yes, but not really when it matters. What would be interesting to know is if the Michigan Lottery uses an electronic system or not to draw the numbers. There's been much debate over using electronics.
