4. Over the universe of positive integers, define p(n): n is prime and n<32. q(n): n is a power of 3. r(n): n is a divisor of 3. (a) What are the truth sets of these propositions? (b) Which of the three propositions implies one of the others? 4. Over the universe of positive integers, define p(n): n is prime and n<32. q(n): n is a power of 3. r(n): n is a divisor of 3.
