So we went from about 40 to 3 in 15.5 weeks. How long will it take to go from 37 to 3, then 34 to 3, then 31 to 1 ? I think the last lottery may be the longest, but that's just a guess.
As for the randomness of the lotto system, even a years worth of draws isn't enough to see similar frequencies for each number. Using probabilities is nice but not predictive to be really useful in choosing numbers unless you look over long periods of time such as years.
I'm not sure but I don't think all the winners had 15 numbers. If true, it shows us that probability is just a guide and unlikely things can and do occur.
