A. Determine whether each sentence is a statement. No available vaccine for COVID 19. 101 is a prime number.  x < y x2 > 0 Lock the door. B. Write each sentence in symbolic form. Represent each simple statement of the sentence with the letter indicated in parentheses. Also state whether the sentence is a conjunction, a disjunction, exclusive or, a negation, a conditional, or a bi-conditional. Today is Sunday (s) and it is my birthday (b).   If x is divisible by 3 (d), then x is an odd number (o).   I am going to answer my assignment (g) if and only if I have an internet connection (i).   All quadrilaterals (q) have exactly four sides (s).
a. Make a truth table for p -a (the inverse of p → q). Your first two columns should be the same as the first two columns of the table for p - q. The last columns of the two tables should be different. Are they? Is ~p → ~q logically equivalent to p q? b. Compare the truth table for ~p - ~g (the inverse of p - q) with the truth table for g-p (the converse of p - g). Are the last columns the same? Are the inverse and the converse logically equivalent?
Determine whether the argument is valid or invalid. No A are B, all B are C, and no C are D. Thus, no A are D. This argument is because
