The average Tengager is statistically more likely to join 100 Hunger Games on here and never win even once than it is for the average Tengager to join any Hunger and then win.
As there are 29 people who fall in the Hungers on here in a cast of 30, x is the number of Hunger Games the average Tengager enrolls in. x is then plugged into this equation below:
29^x
------
30^x
x in this case is 100, so we divide 29^100 by 30^100. The quotient of that probability rounds to about 3.37%.
As for winning any random Hunger, all you have to do is divide 1 by 30, which comes out to about 3.33%.
But hey, even if you're like me and never won Hunger before, don't be disheartened! There's much worse odds than those out there.
