Question
1a.Suppose P is a false statement. Is it ever possible for P ⇒ Q to be false? Explain your answer.
1B.Suppose P is a true statement and that (P ∧ Q) ∨ ¬P is false. What is the “truth value” of Q? (No work need
be included with this question).

- What is the "Principle of Non-Repudiation" according to you?arrow_forwardDescribe the difference between a chained conditional and a nested conditional. Give your own example of each. Do not copy examples from the textbook. Deeply nested conditionals can become difficult to read. Describe a strategy for avoiding nested conditionals. Give your own example of a nested conditional that can be modified to become a single conditional, and show the equivalent single conditional. Do not copy the example from the textbook. The code and its output must be explained technically whenever asked. The explanation can be provided before or after the code, or in the form of code comments within the code. For any descriptive type question. End your discussion post with one question related to programming fundamentals learned in this unit from which your colleagues can formulate a response or generate further discussion.arrow_forwardDirections: For each proof, you must include (i.e., write) the premises in that proof. I do not want to see any proofs without premises. YOU CANNOT USE CONDITIONAL PROOF (CP), INDIRECT PROOF (IP), and ASSUMED PREMISES (A). Additionally, use only the 18 rules of inference found in the text and in the notes. You will lose points if you use any of the inference rules Resolution, Contradiction, Transposition, Idempotence and Identity.arrow_forward
