I have forgotten my probability theory...

Oh, might LJ Brain, help me with this mathematics problem: a man is a demolition derbyist. The probability of him suffering an injury during any one derby is 0.12.
I know that the probability of him suffering an injury in two derbies is ((0.12 + 0.12) - (0.12 * 0.12)). What's the (generalized) formula for him suffering an injury over n derbies?
