To win a lottery through Mathematics?

There are various approaches to increase the chance of winning in a lottery, in a sense, they attempt to encircle the winning lottery numbers. However, we all know that it is mathematically impossible to accurately predict the winning number by sheer calculation. That is because of Gauss’s theorem which require minimum n different equations to solve for n unknown, but any approaches would give less equation than what is needed for solving the unknown.

My solution is to add one more variable into the equations: Luck. That is assume the luck factor is uniformly distributed across day, and that is knowable using methods of testing. (For instance, if u desire large number then throw dice for three consecutive times and get three six. So you are lucky because it has a chance of 1/216, which translated into you have the luck of 1-1/216=215/216 chance of winning.) Theoretically, since we now know the chance of winning and the number you pick then we can reverse-engineer the lottery numbers (use the number auto-selection lottery tickets since it is neutral in a sense). To increase the certainty of the winning numbers, a more sophisticated method is to ask several of your friends to get their luck factor, and ask them to pick the numbers. Since it is known that the chance of you and your friend for winning the lottery, we could thus estimate the number that has the highest chance of winning the lottery by correlate the numbers they pick and the chance of winning.

Actually, I do have an easier method for practice, but that require a sensitivity of your own luck. My method is to choose a day which you had absolutely worst luck. Do not choose the numbers yourself but use auto-selection from the computer(or in any sense that is selected for you by other.) Get as many of those lottery tickets as possible, then eliminate the repeated numbers. Then you have a set of numbers that you know which is extremely unlikely to win(otherwise you would win just by buying these auto-selected number). So what is left is what has a much higher probability to win. Suppose it require you to pick 9 out of 64, what you need is just to find a way to eliminate 55 numbers. If you buy a number of auto-selection lottery tickets, which you just happen to have 55 non-repeating numbers, then you just need to ask a friend to buy the remaining 9 numbers. Make sure s/he will pay you, and make sure you granted me one wish, it is your obligation to fulfill that wish regardless of its nature in case you win the lottery using this method.
