c. Let O= the event that the oil industry investry investry investry investry investry investry investry investry in successful and M= the event that
the municipal bond investment is successful. List the sample points in O and in M.

d. List the sample points in the union of the events (O∪M).

e. List the sample points in the intersection of the events (O∩M) .

f. Are events O and M mutually exclusive? Explain.
