Discrete Mathematical?

just do number 2 and 4

xLet A = {1, 2, 3, 4}, and let r be the relation lessthanorequalto on A. Draw a digraph for r. 2. xLet B = {1, 2, 3, 4, 6, 8, 12, 24}, and let s be the relation "divides," on B. Draw a digraph for s. 3.Let A = {1, 2, 3, 4, 5}. Define t on A by at b if and only if b - a is even. Draw a digraph for t. 4.(a) Let A be the set of strings of 0's and 1's of length 3 or less. Define the relation of d on A by xdy if x is contained within y. For example, 01 d 101. Draw a digraph for this relation. (b) Do the same for the relation p defined by x p y if x is a prefix of y. For example, 10 p 101, but 01 p 101 is false. xLet A = {1, 2, 3, 4}, and let r be the relation lessthanorequalto on A.
