Answer:

Step-by-step 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 "â„¢q → p".

Now;

p            q             ™q             p Vs q              ™q →p

T            T              F                 T                         T

T            F              T                 T                         T

F            T              F                 T                         T

F            F              T                 F                         F

Conclusion:

The given arguments are valid.
