Proposition Expressions
1. **State the problem:** We are given propositions:
- $p$: I bought a lottery ticket this week.
- $q$: I won the million dollar jackpot.
We need to express the following logical expressions as English sentences:
a) $\neg p$
b) $p \lor q$
c) $p \to q$
d) $p \land q$
e) $p \leftrightarrow q$
f) $\neg p \to \neg q$
g) $\neg p \land \neg q$
h) $\neg p \lor (p \land q)$
2. **Translate each expression:**
a) $\neg p$: "I did not buy a lottery ticket this week."
b) $p \lor q$: "I bought a lottery ticket this week or I won the million dollar jackpot (or both)."
c) $p \to q$: "If I bought a lottery ticket this week, then I won the million dollar jackpot."
d) $p \land q$: "I bought a lottery ticket this week and I won the million dollar jackpot."
e) $p \leftrightarrow q$: "I bought a lottery ticket this week if and only if I won the million dollar jackpot."
f) $\neg p \to \neg q$: "If I did not buy a lottery ticket this week, then I did not win the million dollar jackpot."
g) $\neg p \land \neg q$: "I did not buy a lottery ticket this week and I did not win the million dollar jackpot."
h) $\neg p \lor (p \land q)$: "Either I did not buy a lottery ticket this week, or I bought a lottery ticket this week and won the million dollar jackpot."
