Find the conjunction of the propositions :

P : Today is Friday

Q: It is raining today.

Suppose I tell Sue that if she gets a 93% on her final, then she will get an A in the class. Assuming that what I said is true, what can you conclude this case if Sue gets a 93% on her final.

• We have P → Q and P, so Q follows. Sue gets an B.

• We have P → Q and P, so Q follows. Sue gets an A.

• We have P → Q and P, so P follows. Sue gets an A.

• We have Q → P and P, so Q follows. Sue gets an A.

¬(p ⊕ q) is logically equivalent to

• p ↔ q

• p ∨ (p ∧ q)

• (p → q)

• (p ∧ q)

• True

• False

• 0

• 1
