If you go on to the national lottery website, it will tell you the most frequently drawn numbers.

There is more to this question than might first appear. A "rigid" mathematical answer would probably suggest that, in the long run, there would be an equal distribution of probability as regards the appearance of a given number. But what about slight variances in the mechanics of number selection? The idea of "equal probability" assumes no mechanical bias, assumes there is a perfect machine that generates the numbers. There isn't. And remember that this isn't the long run. It's the short run. There haven't been so many drawings that the probability curve can "flatten out" as would be expected over time, even with machinery that isn't "biased" toward or against a number or numbers. There is a lot of "thinking" room on this one.

The fact that the machine, it's parts, or the balls, could change at any time could also skew probabilities over time. Still, the slight degree to which the lottery machine exerts any sort of non-random bias in number picks is probably insignificant in its affect of the expected value of a ticket. If it wasn't, you could bet your pants that we'd have some incredibly rich statisticians walking around.

The original post refers to the National Lottery in the UK, and a link is provided to the page where the most frequently (and least frequently) drawn numbers can be reviewed.
