Conjunction in logic.<br />Hello friends, Welcome to my channel mathstips4u.<br />In this video we are going to learn Conjunction and its truth table.<br />So let’s begin with <br />Conjunction (Ʌ):<br />If p and q are two simple statements, their conjunction is “p and q”, written as p Ʌ q. <br />p Ʌ q is defined to have truth value “true “if both p and q have truth values “true”. In all other cases, p Ʌ q is defined to have truth value “false”. Now we shall see <br />truth table of Conjunction p Ʌ q.<br />p q p Ʌ q<br />T T T<br />T F F<br />F T F<br />F F F<br />Note:<br />1. The words “but”, “yet”, “still”, “moreover”, “while”, “in spite of”,” though”, “even though” are used instead of “and “.<br />2. p Ʌ q and q Ʌ p both are same.<br />Ex. Express following in symbolic form.<br />1. Savita is tall and beautiful.<br />2. Anil and Sunil belongs to same cast.<br />3. The drug is effective though it has side effects.<br />4. In spite of tight security Dena bank were robed.<br />I will solve 1st example, remaining are left for you so try it, and don’t get panic. I will give the solution in my next video. <br />Solution:<br /> 1 p: Savita is tall.<br />q: Savita is beautiful.<br />Symbolic form is p Ʌ q.<br />In this way we have seen conjunction and its truth table.<br />In my next video we are going to learn disjunction and its truth table.<br />If you like my video, please subscribe my channel, like it, share it and comment it.<br />Thanking you for watching my video.<br />
