The complement involves probability. Say the probability of choosing a red marble was 3/10. So the complement, or the chance of not choosing a red marble is 7/10. Think of it as the opposite of the probabilty. You simply subtract the numerator from the denominator and you have the complement. (10-3=7 in this case, then you would put your difference over the probabilities denominator, so it would be 7/10.)
