One of the basic requirements of probability is A)for each experimental outcome E_i, we must have P(E_i) $\ge$ 1 B)P(A) - P(A^c) - 1 C)if there are k experimental outcomes, then P(E₁) + P(E₂) + ... + P(E_k) = 1 D)both P(A) = P(A^c) - 1 and if there are k experimental outcomes, then P(E₁) + P(E₂) + ... +P(E_k) = 1
