Consider the family of sets S= [{1,5, 6}, {2,4, 6), (4, 5, 6), {2, 5, 6}, {3,4, 5}, {1, 4, 6}]. (1.1) and let Y - (1,3, 4, 5}. Define the relation Ron S by (A, B) ER = A\Y = B\Y, where A, B are arbitrary elements of S. (1) (a) Since for every A ES A\Y = \Y, where ? = B ,the relation R (here and below in (b-d), please type is or is not in the input field below) is reflexive. (b) Given any A, BES, we have that A\Y = B\Y = B\Y= \Y where and hence the relation R is symmetric. (c) For every A, B, CES, (A\Y = B\Y) and (B\Y = C\Y) implies A\Y = \Y, where al= ,and hence the relation R is transitive. (d) Accordingly, by (a,b,c), the relation R is an equivalence relation on S. (11) Find the matrix MR of the relation R (please enter the matrix row-by-row in the six input fields below, when entering each row, seperate the entries by single spaces; understandably, the i-th row/column of the matrix MR must correspond to the i-th set A, in the list of the elements of S given in Eq.
