Copy this into SOL Binder(G.1)- day 18 Let p = “n is an integer and n² is divisible by 4” Let q = “n is divisible by 4” p → q means “If n is an integer and n² is divisible by 4, then n is divisible by 4.” What is a counterexample to p → q ? In this case, n = 10 is a counterexample because 10² = 100 and 100 is divisible by 4, but 10 is not divisible by 4. Other possible answers: 2, 6, 14, 18, etc.
