Please help, thank you

An E/R diagram that includes a 3-way relationship R connected to the entity sets E1, E2, and E3 is converted into a relational database. Let m, n, and k be the number of tuples in some valid instances of E1, E2, and E3, respectively. In each of the following cases, determine the minimum, maximum, or exact (when applicable) number of tuples in R. We refer to this number as the size of R, denoted as |R|. For the size of R determined, what condition(s) must hold on the values m, n, and k.

Question: The connection from R to E1 is a sharp arrow and from R to E2 is a round arrow (that is, exactly 1).
