3. 100% SUCCESS IN JEE MAIN AND ADVANCED (IIT-JEE) SET THEORY IN PROBABILITY A n B or AB represent the occurrence of both A & B simultaneously "Au B" or A B represent the occurrence of either A or B. (i) For two events A and B A B (a) Pat least one out of them) P(A) + P(B) PAnB) (b) P (exactly one out of them)-P(A)+ P(B)-2 P(AnB) For three events A, B and C P(at least one out of them) P(A) +P(B)+P(C)-P(AnB)-P(Bnc)-P(CnA)+P(AnBnc) (ii) P(A) 1-P(A) SUCCESS IN JEE MAIN ER.

6. 100% SUCCESS IN JEE MAIN AND ADVANCED (IIT-JEE) Example In throwing of a die, let A be the event 'an odd number turns up', B be the event 'a number divisible by 3 turns up' and C be the event 'a number s 4 turns up Then find the probability that exactly two of A, B and C occur Solution Event A = {1, 3, 5), event B = {3, 6} and event C = {1, 2, 3, 4} Thus P(exactly two of A, B and C occur) SUCCESS IN JEE MAIN ER.
