Each statement accurately describes fundamental principles of probability. A) and B) express the same concept using different terms: the probability of not A is the complement of the probability of A, which is mathematically represented as 1 - P(A). C) correctly states that an impossible event has a probability of zero, and D) correctly states that a certain event has a probability of one.
