One of the basic requirements of probability is A)for each experimental outcome E_i, we must have P(E_i) 1 B)P(A) = P(A^c) - 1 C)if there are k experimental outcomes, then $\Sigma$P(E_i) = 1 D)$\Sigma$P(E_i) 1

The requirement that the sum of probabilities of all possible outcomes is equal to 1 is one of the fundamental axioms of probability. This is expressed as F1F1F1S1F1F1F10P(E_i) = 1, which is option C. Option A is not completely clear and uses incorrect symbols. Option B is incorrect because it does not make sense to subtract one probability from another. Option D is incorrect because it is the same as option C, but with a typo in the question stem.
