A snap-shot of Mega Millions winning numbers appears below:
Now, I am probably going to get whacked for pointing this out, but look at the pattern in last 20 draws below: 7 comes up as the mega number four times. Twice in quick succession, there is a sequence of 4; 7; 6. 10 came up three times:

I am guessing that office pool players use quick-pick "random number" tickets; just to speed up the process of buying the tickets? When I buy 10 or 20 quick-pics, I notice that their mega numbers tend to be very repetitive, and not spread out from 1 to 15. That is a "problem" when those mega numbers fall outside the latest pattern in the mega number drawings. Yes, I said pattern, because if you look at the last 20 or so drawings, you will notice a repetitive pattern in the mega numbers. That is until the pattern resets; and there is no predicting when that will happen, or how far it will jump.
Yes, such patterns are possible in a random system, but if you page back into previous winning numbers you will find that this drawing a subset of repetitive numbers happens extremely often. So often, I have steaks of getting my money back on the cost of the tickets...
Now, the previous 20 draws had a different pattern, so as we have just had 20 draws, the pattern may be about to reset, meaning, the mega number tonight may not be a 6, 7 or 10 as I predicted for a continuation of the current pattern. That is why I buy both quick-picks and choose my own numbers when the prize gets to be "up there".
