I'm insane enough to have done the math before, more as a mental exercise.
It goes something like this... 48 numbers pick 5, for example
48X47X46 X45X44
divide by number of ways that can hit ( don't feel like thinking now).
I got exact number they put in powerball literature doing that, feels good to figure it right.
useful logic , but too much for most sports betting spots, just know what y'all need, but reach back to analyze crazy stuff.
You need to know there are 1024 combos in a 10 teamer, and variations down to 4 in a 2 teamer.
Value of a half point matters.
You don't need to be able to figure lotto odds, but if you can at least try, it's cool.
No penalty for trying.
