Q1 of 62 Page 1346

Mark (√) against the correct answer in each of the following:

If A and B are mutually exclusive events such that P(A) = 0.4, P(B) =x and P(A ∪ B) = 0.5, then x = ?


If A and B are mutually exclusive events then,


P(A) = 0.4, P(B) = X


And P(A B) = P(A)+P(B) = 0.5 = 0.4 + P(B)


⇒ P(B) = 0.1
