Okay,
ken_matthews
I thought of another way to try and help you understand during my commute.
You have been conflating the properties of the integers 1-70 (their order and differences) with the properties of the game.
I have been trying to explain that the properties of these numbers have no bearing on the chances of winning the game. You've come back with math and code that, still, has not made your point, though you believe it has.
Consider this:
The integers from 1-70 are just convenient labels for the balls. Nothing more.
The formula for combinations, nCr = (n!)/(r!(n-r)!), counts how many ways r elements can be selected, without order, from a set of n elements. That's elements, in general. Not necessarily numbers.
So when you compute 70C5, you're thinking of choosing five numbers, yes. But that formula works for counting and choosing anything.
Instead of numbers, let's print each of the 70 balls with its own unique snowflake. We're still choosing 5 of 70. It's the exact same game as Mega Millions, just different labels. Each play has the exact same probability of winning, 1/12103014.
Or, let's print each of the 70 balls with the portraits of 70 different people. Still the same game. Same probability of winning.
Or 70 unique portraits of one person. Same game.
Or pictures of 70 different musical instruments. Same game.
Or depictions of the unique sinusoidal sound wave of each of those instruments. Same game.
Or 70 different colors. Same game.
Or photographs of 70 different high schools from across the USA. Same game.
Or cover art from 70 different comic books. Same game.
Or photographs of the crushed and compacted cubes from 70 different junk cars. Same game.
Or the thumbprints of 70 different people. Same game.
Or the retinal scans of 70 different people. Same game.
Or the genomes of 70 different species. You'd have to print really really small, or have huge balls, but same game.
All that matters is that we can tell 70 balls apart from each other. That's it. How we choose to label them has absolutely no effect on the chances of winning the game. Any labels will do, even if they lack the properties (such as order) of the integers 1--70. The lottery uses numbers out of convenience. It's easier to read and print numbers than to compare sine waves, photographs, snowflakes, etc. But the fact that those numbers have an order on the number line does not affect the odds of winning the game.
The peaks in your graph come from the order of the numbers. They do not indicate anything of the game, or increased odds of winning it. If the balls were printed with 70 unique thumbprints, you wouldn't be able to order them as Ball 1, Ball 2, etc like with the numbers, or discuss whether they are adjacent or spread out, or have your graph with the balls and their peaks.
But it would be the same game.
