The following problem is that of Discrete Mathematics. Consider the following implication, where n stands for an unknown integer.“If n is divisible by 10, then n is divisible by 5.” a. Write the equivalent “or” form of this implication as an English sentence. b. Write the logical negation of this implication as an English sentence. (Do not use “It isnot the case that…”)
In the following question, the domain of discourse is a set of male patients in a clinical study. Define the following predicates: • P(z) : z was given the placebo • D(z) : z was given the medication • M(z): z had migraines Translate cach of the following statements into a logical expression. Then negate the expression by adding a negation operation to the beginning of the expression. Apply De Morgan's law until cach negation operation applices directly to a predicate and then translate the logical expression back into English. Sample question: Some patient was given the placebo and the medication. 3r (P(z) ^ D(z)) • Negation: ¬ar (P(z) ^ D(z)) Applying De Morgan's law: ¥z (¬P(z) V ¬D(z)) English: Every patient was either not given the placebo or not given the medication (or both).
