TRUE OR FALSE.  The possible letter grade for a course is A+, A, A-, B+, B, B-, C+, C, C-, D+,D, D- and F. Let event E1 represent the case that you receive a grade equal or higher than B, i.e. E1 = { A+, A, A-, B+, B }. Let event E2 represent the case that you receive a non-failing grade equal or lower than B, i.e. E2 = { B, B-, C+, C, C-, D+, D, D-}. Determine whether the following statement is true. Then event E1 is the complement of event E2.
