E?
1. P+3 is a prime number
If P = 2, P+3 = 5 (Prime) Ans: P is prime
If P = 4, P+3 = 7 (Prime) Ans: P is not prime
2. P^2+3 is a prime number
If P = 2, P^2+3 = 7 (Prime) Ans: P is prime
If P = 4, P^2+3 = 19 (Prime) Ans: P is not prime
Together
If P = 2, P+3 = 5 (Prime), P^2+3 = 7 (Prime) Ans: P is prime
If P = 4, P+3 = 7 (Prime), P^2+3 = 19 (Prime) Ans: P is not prime
