please answer correctly with full explanation.

Consider an E/R diagram that has a 3-way relationship R connected to the entity sets E1,E2, and E3. If a table corresponding to E1 has 3 tuples, to E2 has 4 tuples, and to E3 has 2 tuples, what is the maximum number of tuples we can have in an instance of table corresponding to R ? (Your answer would be an integer of the form n.)
