7. 100% SUCCESS IN JEE MAIN AND ADVANCED (IIT-JEE) The word "AND" : Any two statements can be connected by the word "and" to form a compound statement. Ex. 42 is divisible by 5, 6 and 7 The component statements of this statement are- p : 42 is divisible by 5. q 42 is divisible by 6. r: 42 is divisible by 7. Clearly statement p is false, while the q and r are true statements. Ex. 9 > 4 and 2 < 7 The component statements of this statement are p:9>4 q 2 7 Clearly p, q are true statement SUCCESS IN JEE MAIN ER. VINEET LOOMBA (IIT RooRKEE)

8. 100% SUCCESS IN JEE MAIN AND ADVANCED (IIT-JEE) Ex. 5 < 12 and 15<7 p: 5 <12 q: 15 < 7 Clearly p, q are false statements The compound statement with word "and" is true if all its component statements are true The compound statement with word "and" is false if any or all of its component statements are false. The compound statement "p and q" is denoted by "p ^ q". SUCCESS IN JEE MAIN ER. VINEET LOOMBA (IIT RooRKEE)

10. 100% SUCCESS IN JEE MAIN AND ADVANCED (IIT-JEE) The word "OR" Any two statements can be connected by the word "OR" to form a compound statement. Ex. 125 is a multiple of 7 or 8. Its component statements are. p: 125 is a multiple of 7 q 125 is a multiple of 8 clearly, both p and q are false Ex. The earth is round or the sun is hot Its component statements are: p: the earth is round q: the sun is hot. Clearly, both p and q are true. SUCCESS IN JEE MAIN ER. VINEET LOOMBA (IIT RooRKEE)

11. 100% SUCCESS IN JEE MAIN AND ADVANCED (IIT-JEE) The compound statement with word "or" is true if any or all of its component statements are true The compound statement with word "or" is false if all its component statement are false * The compound statement "p or q" is denoted by "p v q" SUCCESS IN JEE MAIN ER. VINEET LOOMBA (IIT RooRKEE)

12. 100% SUCCESS IN JEE MAIN AND ADVANCED (IIT-JEE) Negation of compound statements: If p and q are two component statements then the negation of the compound statement (i) (p or q) is p and q (p v q)-p q (ii) ~(p and q) is ~ p or ~ q ~(p ^ q)--p v-q SUCCESS IN EE MAIN ER.
