Math Problem Statement

Use p, q, r, and s as defined below: p: Today is Thursday q: It is cold outside r: I am feeling tired s: I am not going out for dinner Write an English sentence: (p ∧ (q ∨ r) → s)

Solution

The image you provided shows a logic-based question from a homework assignment. The problem defines the following propositions:

  • pp: Today is Thursday
  • qq: It is cold outside
  • rr: I am feeling tired
  • ss: I am not going out for dinner

The task is to translate a logical expression into an English sentence:

The logical expression given is: p(qr)sp \land (q \lor r) \to s

Breaking this down:

  • p(qr)p \land (q \lor r): This means "Today is Thursday, and either it is cold outside or I am feeling tired."
  • s\to s: This means "then I am not going out for dinner."

So, the full English sentence becomes:

"If today is Thursday, and it is cold outside or I am feeling tired, then I am not going out for dinner."

In the provided image, the option selected seems to be option (a), which is correct.

Would you like further explanation on any part of this?

Here are five related questions to expand on this:

  1. What does the logical operator \land (AND) signify in a proposition?
  2. How does the \lor (OR) operator affect a compound statement?
  3. Can you explain the significance of the implication operator \to?
  4. What happens to the truth of a statement if both qq and rr are false?
  5. How can you negate the given proposition to express the opposite?

Tip: Always break down complex logical statements into smaller components for easier translation into natural language.
