Detailed explanation-1: -The logical negation symbol ¬ or is one of the statement connectives or operators that can be used to form new compound statements from two or more statements. It simply reverses the truth value of any statement in front of which it appears.
Detailed explanation-2: -(vii) The symbol ‘∉’ stands for ‘does not belongs to’ also for ‘is not an element of’. Therefore, x ∉ A will read as ‘x does not belongs to set A’ or ‘x is not an element of the set A’.
Detailed explanation-3: -The conjunction of the statements P and Q is the statement “P and Q” and its denoted by P∧Q. The statement P∧Q is true only when both P and Q are true. The disjunction of the statements P and Q is the statement “P or Q” and its denoted by P∨Q. The statement P∨Q is true only when at least one of P or Q is true.
Detailed explanation-4: -Read “p and q.” ● p ∧ q is true if both p and q are true. ● Also called logical conjunction.
