Write the relation R from X to X relative to the ordering X: a, b, c, d given by the 1000 01 10 matrix, as a set of ordered pairs. A = 01 10 00014. Let R1 be a relation from X = {1, 2,3} to Y = {x, y} defined by R1 = { (1, x), (2, y), (3, x), (3, y) } ; and let R2 be the relation from Y to Z = {a, b, c} defined by R2 = {(x, a), (x, b), (y, b), (b, z) }; find (a) The matrix A, of the relation R1 (relative to the given orderings). (b) The matrix A2 of the relation R2 (relative to the given orderings). (c) The matrix AlA2. (d) Use the result of part (c) to find the relation R2 0 R1. 35. Write the relation R from X: w, x, y, z 1010 0 0 0 0 to Y: a, b, c, d, given by the matrix, A = 1010 0 0 01 as a set of ordered pairs and decide whether the relation is reflexive, symmetric, transitive, and/ or equivalence relation.6. Find the matrix of the relation R from X to Y relative to the orderings given. R = {(6, 2), (E, 1), (a, 3), (3, 2), (E, 3) } ; ordering of X: a, 3, 6, E; ordering of Y : 2, 3, 1,\f\fIn how many ways can eight distinct books be divided among three students if Francis gets four books, and Bob and Alice each gets two books
