Consider the following statement: Statement A: ∀ integers m and n, if 2m + n is odd then m and n are both odd. Disprove Statement A. That is, show that Statement A is false
Find the error in the following argument: Theorem. All computer programs contain the same number of bugs. Proof. If we show that any set of n programs contains the same number of bugs, then we have proved the theorem. We argue by induction on n. If n=1 then in any set of 1 program, all the programs contain the same number of bugs, so the statement is true, in this case. Now suppose that for every set of programs containing less then n programs, all the programs have the same number of bugs. Let DD be a set of n programs p1,p2,…,pn. Now the set D1={p2,…,pn} contains n−1 programs and hence they all contain the same number of bugs, by the induction hypothesis. Similarly the set D2={p1,…,pn−1} contains n−1 programs and hence they all contain the same number of bugs. In particular p1 and pn contains the same number of bugs as the other programs in the set. Hence all the programs contain the same number of bugs.
Below are some statements; the domain of each is the set of all integers. For symbolic statements, thenegation symbol (¬) must not apear in your answer. For English statements, don’t use “It is not the casethat” or just the word “not” to form the negation.For each one, state whether the statement is TRUE, FALSE, or CAN’T BE DETERMINED. For all that onesthat are TRUE or FALSE, state the negation:1.∃n(nis even)2.∀a∀b(3a≥2b)3.∀a∃b(ab= 1)

Q2: Prove the following statements by Contradiction. (1) The difference of any rational number and any irrational number is irrational. Student answer:
True or False: for each of the following statements, decide if it is true or false. If it istrue, then provide a proof; if it is false, provide a counterexample.(a) For events A, B, it is always the case that Pr(Bn.A) < Pr(B).(b) For events A, B with Pr(A) > 0, it is always the case that Pr(B | A) < Pr(B).
What does the statement 'guess == 5' do? a. assigns the value 5 to guess b. if guess is not equal to 5, it assigns 5 to guess. If it is equal, it leaves guess alone. c. tests for inequality, resulting in True when guess is not equal to 5 d. tests for equality, resulting in True when guess is equal to 5 What does 'num > 5' test for? a. the value in num is greater than or equal to 5 b. the value in num is greater than 5 c. the value in num should be greater than 5 d. num will be set to 5 How are letters stored in memory? a. as ones and zeros using ASCII encoding b. directly c. letters cannot be stored in memory d. using public key encryption
Identify p, g, and r if necessary. Then translate each argument to symbols and use a truth table to decide if the argument is valid or invalid. If it snows, I can go snowboarding, It did not snow . I cannot go snowboarding.
