Suppose that we have a sample space SE1, E2, E3, E. Es where E denotes the sample points. Following probability assignments apply: P(E) = 0.05, P(E2) = 0.15, P(E3) = 0.2, P(E4) = 0.25, P(E)=0.3. a. Does the above assignment of probability make sense to you? And if not then why? b. Ignoring the errors (if any) what is P(AUB) if A= {E, Es} and B = {E, E}?
