2 (2) Starting with sets A, B, C, D, E and F with a := v(A), b := v(B), a = v(C), d == v(D), e := v(E) and f := v(F), use as many of the operations in the list below as many times as you wish: {( ),,un, \\ II , LI , Enc ( A, B ), ( ), = } (i) to construct a set S whose cardinality appears below, and v (S) = a+b-cxd +elf (ii) to construct word-problems whose solutions require counting the number of elements of the sets you constructed in (i). Note that the numbers are such that V (S) EN Draw a formation-tree for the expression on the facing side. Draw a formation-tree for the expression that you have constructed. Prove that the cardinality of the set that you have constructed equals the given expression. Write the word problem step by step respecting the formation-tree of the expression that you have constructed
