To prove that the statements p1, p2, p3, and p4 are equivalent, is if sufficient to show that the conditional statements p4→p2,p3→p1,and p1→p2 are valid? If not, provide another collection of conditional statements that can be used to show that the four statements arc equivalent.

SOLUTION

Step 1

We have to show whether it is possible to say that the statements are equivalent by the conditional statements
