Q4.a. Assume A and B are subsets of some universal set U. Complete the following member- ship table and briefly explain how we can conclude from it that the following equation is a set identity: (A − B)U(BUC) = (AUC) NB Q4.b using the Laws from the Table of Important Set Identities. You may use one or two laws at each step, and you must write the name of the law(s) used at each step. Do not combine more than two laws in one step. Do not omit necessary parentheses.

Variables: Which of the following is NOT true about universal quantifiers? The phase that indicates a universal quantifier is “for all”. The symbol we use for universal quantifier is∀. The elements of a given set satisfy all property. The symbol we use for universal quantifier is∃. Variables: Which of the following statements is true about existential quantifiers? The symbol we use for existential quantifiers is∃. A property is true for all of the elements in a set. The phrase we use for existential quantifiers is 'for all.'

Write it in Racket Define a function (bst? n) to test for membership to determine if a collection of nodes satisfies the bst property (is a bst). The BST property is that for any node n in the bst: all nodes to left must have value < (node-value n) all nodes to right must have value > (node-value n) Skeleton for function (define (bst? n) (cond )) The function can be defined as one big conditional with multiple cases. Some of the cases are base cases, others will require a recursive call to bst? There is more than one way to develop the cases, but here are some starting point ideas. If n is null or empty, result is true #t else if n is not a node structure, then result is false #f else if n has no child nodes, then result is true #t else if n has one child on the left, then result is n.left.value < n.value AND bst?(n.left) is true else if n has one child on the right, then result is n.right.value > n.value AND bst?(n.right) is true else if n has two children, then result is…

Define function p:cat represents set concatenation ◦, which concatenates every pair of strings from both sets using racket. We can specify set concatenation as p1 ◦ p2 = {u · v | u ∈ p1 ∧ v ∈ p2}. Alternatively, we give an inductive specification: ∅ ◦ p2 = ∅ p1 ◦ p2 = prefix(u, p2) ∪ (p'1◦ p2) if p1={u} ∪ p'1.
Sets are collections (1) without defined order and (2) not allowing duplication. Multisets, also called “bags” are collections without defined order but which permit duplication, i.e., more than one element. We define the function #(a B) to be the number of occurrences of the element a in the bag B. For example, #(1, [1 1 2 3 4 4 5]) is 2 and #(5, [1 1 2 3 4 4 5]) = 1. Bag union and intersection are defined in terms of #. bag-union: List × List -> ListThis function should take as arguments two lists representing bags and should return the list representing their bag-union. bag-intersection : List × List -> ListThis function should take as arguments two lists representing bags and should return the list representing their bag-intersection. Allowed functions.
