1. If two events are independent, then:?

a.ALL the resulting outcomes from each of the two events MUST be mutually exclusive.


b.The sum of the probabilities of ALL the resulting outcomes MUST equal 1


c.AT LEAST TWO of all the resulting outcomes MUST intersect


d.All of the above are correct


e.NONE of the above are correct





2.Which of the following statements is (are) ALWAYS true?


a.-1 ≤ P(Ei) ≤ 1


b.P(A) = 1 – P (Ac)


c.P(A) + P(B) = 1


d.Both B and C


e.None of the above answers are correct





3.A single event has two mutually exclusive outcomes: A and B, and each outcome has a nonzero probability. If the event is initiated and outcome A has occurred, then the probability of the occurrence of outcome B is


a.one


b.any positive value


c.zero


d.any value between 0 to 1


e.None of the above





4.One of the basic requirements of probability is
