You want to start by deciding and experimenting with however many different possibilities there is for the red balls to settle in. To help with this we tried mirroring and reversing patterns to make more. We came up with the answer of 18 different positions. You must then figure out how many of those positions can no red balls be in the corners. The answer to that is only one position! So the formula would be approximately 1 in 18 tries that you would lose the game.
