Answer: A or C

The probability of every event is at least zero.

(For every event A, P(A) >= 0. There is no such thing as a negative probability.)

The probability of the entire outcome space is 100%.

(P(S) = 100%. The chance that something in the outcome space occurs is 100%, because the outcome space contains every possible outcome.)

If two events are disjoint, the probability that either happens is the sum of the probabilities that each happens.

(If AB = {}, P(AUB) = P(A) + P(B).)

Explanation:

the probability that an event A does not happen is 100% minus the probability that A happens:

My answer P(Ac) = 100% - P(A).
