It is
really simple.
I said "If you have a 10% chance of winning a contest every time you play you have a better chance of winning "at least once" if you play 3 times than if you play only once."
Now here is the math.
If you have a 10% chance of winning a contest and play one time only your chance of winning at least once is just that 10%.
If you have a 10% chance of winning a contest and play twice your chance of winning at least once is now 1 minus the chance of losing both times. The chance of losing both times is .9*.9 = .81. So the chance of winning at least one game is 1-.81 = .19 = 19%
If you have a 10% chance of winning a contest and play three times your chance of winning at least once is now 1 minus the chance of losing all three times. The chance of losing all three times is .9*.9*.9 = .729. So the chance of winning at least one game is 1-.729 = 27.1%
27.1% is higher than 10%.
