The complement rule states that the probability of an event A occurring is equal to 1 minus the probability of A not occurring. This is mathematically represented as P(A) = 1 – P(not A). Choice B correctly represents this rule. Choice A looks like a variation of the subtraction rule. Choice C looks like the multiplication rule. Choice D does not represent any statistical rule.
