MAT 230 Module Two Problem Set
Problem 1
Part 1. Indicate whether the argument is valid or invalid. For valid
arguments, prove that the argument is valid using a truth table. For
invalid arguments, give truth values for the variables showing that the
argument is not valid.
Part 2. Converse and inverse errors are typical forms of invalid arguments. Prove that each argument is invalid by giving truth values for
the variables showing that the argument is invalid. You may find it easier to find the truth values by constructing a truth table.
Part 3. Which of the following arguments are invalid and which are
valid? Prove your answer by replacing each proposition with a variable
to obtain the form of the argument. Then prove that the form is valid
or invalid.
