You can't even code a simple random number picker correctly.

Not that I defend the appalling state, because I don't. But man the armchair developers are out in full force with these speculations.

It’s not even necessary to be an armchair developer though, you could be a pram developer and make this work effectively.

Look, as someone with very little ability, Here’s the code.

x = (rand() * number of tickets) ;

[SnowVix]

x = (rand() * number of tickets) ;

rand() calls from zero through upper, so this hilariously shows exactly how the problem may have happened in the first place, and isn't in fact any demonstration of how you would fix it.
