Discrete Mathematics assistance needed.
Hello;

I am over my head in math. I have tried reading my text book to achieve a viable answer; however, I am incorrect in my answers.

1.) Construct a truth table for each of the following compound statements:
a.) (p∧q) ∨ ((¬p) → q)
b.) ¬ (p∧(q∨p)) ↔ p

2.) If p and q are statements, then the compound statement p⊻q (often called the exclusive or) is defined to be true if and only if exactly one of the p, q is true; that is, either p is true or q is true, but not both p and q are true. Construct a truth table for (p⊻((¬p)∧q))∨q.

Any assistance is greatly appreciated. As I have already stated; I am way over my head.

Hey rtrumpow.

Can you show us a truth table for Q1?

Start with a truth table and make columns for what you have inside the parentheses. Then slowly work your way out.

Hint: You may need more than four rows for your final solutions.
