Discrete Math (Full Course: Sets, Logic, Proofs, Probability, Graph Theory, etc) - Disproving implications with Counterexamples

Counterexamples are one of the most powerful types of proof methods in math and philosophy. When you give a counterexample, you are demonstrating that some claim if false. For instance, if I say that every prime number is odd, I can disprove that claim by observing that 2 is a prime which is even. In this video we're going to talk about when you can use counterexamples, the structure of that type of proof, and see some examples. ►Full DISCRETE MATH Course Playlist: https://www.youtube.com/playlist?list=PLHXZ9OQGMqxersk8fUxiUMSIx0DBqsKZS Other Course Playlists: ►CALCULUS I: https://www.youtube.com/playlist?list=PLHXZ9OQGMqxfT9RMcReZ4WcoVILP4k6-m ►CALCULUS II: https://www.youtube.com/playlist?list=PLHXZ9OQGMqxc4ySKTIW19TLrT91Ik9M4n ►CALCULUS III: https://www.youtube.com/playlist?list=PLHXZ9OQGMqxc_CvEy7xBKRQr6I214QJcd ►LINEAR ALGEBRA: https://www.youtube.com/playlist?list=PLHXZ9OQGMqxfUl0tcqPNTJsb7R6BqSLo6 ► Want to learn math effectively?
