DISCRETE/LOGIC MATH please show work and explain 3. Let A, B, C be sets. Use the...
This is a discrete math question: Exercise 5. Let A and B be sets. Prove or disprove: AAB| = |A - B+B - AL. Claim. Proof
circuits snd binomial sets MATH 247: Homework 3 1. For the circuit: VS give both a simplified symbolic expression and the corresponding simplified elecult diagram 2. For sets A, B and C, consider the statement A-(B-C) = (A - B)-(A-C). (a) Provide a counterexample that shows the statement is not always true. (Make sure to demonstrate way your counterexample is valid.) > (b) Use a table to prove that one is a subset of the other 3. Consider the following:...
(discrete math) i need help with sets 15. Let A={1,3,5,7,9), B - {3,6,9), C= {2,4,6,8) and U - {1,2,3,4,5,6,7,8,9). Find: a. AUB b. AnB And e. A-B f. P(B)
Discrete math for Computer Science, Sets: Binary relations / Functions Please show work 2. Let S = {0, 2, 4, 6), and T-1, 3, 5, 7). Determine whether each of the following sets of ordered pairs is a function from S to T. If so, is it injective, surjective, and bijective?
#9-11 please 9. Let A and B be disjoint sets in the universe U. Let C be a proper subset of A. (a) Draw a Venn Diagram representing this information. (b) What is BAC? 10. Let A be a set in the universe U. (a) Draw a Venn Diagram and shade in the region A. Then draw another Venn Diagram with the same set A, but shade in A'. (b) What is A'U A? 11. Give an example of three...
help please and thank you 3. The symbole, also called XOR, is the logic operation modeling the exclusive OR. We will define Peas -(P Q). (a) Give a truth table that fully describes P Q. (Just like the other logic operations were defined in Lecture 3.) (b) State what it would mean for 2 to be commutative and associative, and then prove or disprove your statements. (c) Let A, B be sets. Prove that r e AAB iff (x E...
need help with proving discrete math HW, please try write clearly and i will give a thumb up thanks!! Let A and be B be sets and let f:A B be a function. Define C Ax A by r~y if and only if f(x)f(y). Prove thatis an equivalence relation on A. Let X be the set of~-equivalence classes of A. L.e. Define g : X->B by g(x) Prove that g is a function. Prove that g is injective. Since g...
Discrete math show all work please Use mathematical induction to prove that the statements are true for every positive integer n. n[xn - (x - 2)] 1 + [x2 - (x - 1)] + [x:3 - (x - 1)] + ... + x n - (x - 1)] = 2 where x is any integer = 1
This problem is dealing with Discrete Math. Please answer fully and clearly, and show/explain all steps or proofs that you state in the answer. 4. Let (G, w) be a connected graph with weights on edges so that all weights are distinct positive real numbers. Suppose we find a MST (minimum spanning trees ) in G by using Prim's algorithm. Prove that no matter what vertex we begin with in Prim algorithm, the set of all weights on edges in...
Discrete Math Please Help parts a and b Let A = {0,1}, and consider A*, the set of all bitstrings. Let s,t E A*. Consider the relation R, where s Rt if and only if bitstring s is a prefix of bitstring t. For example, 00111 R 0011101 because all the bits in the first bitstring make up the first five bits in the second string: 0011101. Classify the following statement as true or false: The relation R is antisymmetric....
