Ovo
Statement 1: It is false that "we are having pizza for dinner or
it is Sunday."
O-0
Statement 2: If we are having pizza for dinner, then it is not
Sunday.
(b) Complete the truth table below. Use T for true and F for false.
You may add more columns. But those added columns will not be graded.
Your answers from part (a) will fill in here.

(c) Are Statement 1 and Statement 2 equivalent? Why or why not? Choose the best answer.
Statement 1 and Statement 2 are equivalent. This is because the truth value of
O Statement1 is the same as the truth value of Statement 2 for each true-false
combination of p and q.
Statement 1 and Statement 2 are equivalent. This is because the two statements are
made from p and q, and any two statements made from p and q are equivalent.
Statement 1 and Statement 2 are not equivalent. This is because the two statements
are different, and different statements cannot be equivalent.
Statement 1 and Statement 2 are not equivalent. This is because the truth value of
O Statement 1 is different from the truth value of Statement 2 for at least one true-false
combination of p and q.
