Question
The Table
The Table
Hello! I was wondering if you could clarify whether or not my answers are correct. I don't want to turn them in, and then wind up having to do them all over.

Problem 1:
Write the statement in symbolic form and construct a truth table:
It is false that Wanda Garner is the president or that Judy Ackerman is the treasurer. (I attached the photo of the table I made. Sorry if it looks kind of messy.)

Problem 2:
Use De Morgan’s laws to determine whether the two statements are equivalent:
∼p ∨ ∼q, ∼(p ∧ q)

My answer: ∼p ∨ ∼q = ∼(p ∧ q)
(Not P) or (Not Q) = Not (P and Q)
They are equivalent

Now, on Problem 3, I need a little assistance:
Determine the truth value of the statement when p is T, q is F, and r is F: (p ∨ q) ↔ (∼r ∧ p)

Could you help me, please? Thanks!

Answer
The first two are ok.

Look what you have sent me for the third problem:

"Now, on Problem 3, I need a little assistance:
Determine the truth value of the statement when p is T, q is F, and r is F: (p ∨ q) ↔ (∼r ∧ p)"

I can't answer this unless I know what logical connectives go in for those squares
