Q. 9

A and B are two independent events. The probability that A and B occur is 1/6 and the probability that neither of them occurs is 1/3. Find the probability of occurrence of two events.

Answer :

P(AB)=









6P(A)2–5P(A)+1=0


6P(A)2–3P(A)–2P(A)+1=0


[2P(A)–1][3P(A)–1]=0


2P(A)–1=0


2P(A)=1



3P(A)–1=0


3P(A)=1
