Suppose that we have a sample space S = {E, E, E3, E4, Es, Es, E7}, where E,, E2,., E, denote the sample points. The following probability assignments apply: P(E1) = 0.05, P(E1) = 0.15, P(E3) = 0.10, P(E4) = 0.20, P(E5) = 0.10, P(Es) = 0.10, and P(E7) = 0.30. Assume the following events when answering the questions.
