.

You can't answer number 5. You are given the number that have MORE than 15 years service, but the complement of that set is the number that have LESS than or EQUAL to 15 years service. So to answer number 5 you must find the number of single males with less than or equal to 15 years service and subtract the number of single males with EXACTLY 15 years service. You cannot determine the cardinality of that last set from the data given.
