Determine the validity of each the following arguments. If the argument is one of those listed in the text, name it.

a. She uses e-commerce or she pays by credit card.
b. She does not pay by credit card.
c. She uses e-commerce

Answer 1

Explanation:

We will design a truth table to determine the validity of the provided arguments.

As a result, we have the following presumption:

• Assume "p" stands for "she shops online(e-commerce)" and "q" stands for "she pays with a credit card."
• Also, she utilizes e-commerce or pays with a credit card, resulting in "p Vs q".
• She doesn't pay with a credit card, therefore -commerce becomes "™q → p".

Now;

p q ™q p Vs q ™q →p
