If A and B be two events associated with a random experiment such that P(A) = 0.3, P(B) = 0.2 and P(A B) = 0.1, find

(i)


(ii)


(i) Given : P(A) = 0.3, P(B) = 0.2 , P(A B) = 0.1


To find :


Formula used : = P(B) - P(A B)


Substituting in the above formula we get,


= 0.2 – 0.1


= 0.1


= 0.1


(ii) Given : P(A) = 0.3, P(B) = 0.2 , P(A B) = 0.1


To find :


Formula used : = P(A) - P(A B)


Substituting in the above formula we get,


= 0.3 – 0.1


= 0.2


= 0.2
