Enough with all the math.
Playing the lotto is not about math or odds. It's all about philosophy.
When I say that your chances doubled dosnt sound right its because its ridiculous. When dealing with such a large number of decimal points, doubling your chances is not considered quantifiable.
It's compared to what we call in halacha speak a "rov beteva" . in other words, for eg. of course mathematicians and statisticians could quantify all the animals in the world and tell you the odds of the animal not being a treifa.
But the numbers are irrelevant. You're not winning. Period. Finished. It doesn't matter if you buy 1 or 5 tickets. It is neged hatevah to win. Impossible.
