1.	If A and B are two mutually exclusive events such that P(A) = (1/2) and P(B) = (1/3), find P(A or B).
Answer» P(A) = 1/2, P(B) = 1/3 We know, P(A or B) = P(A) + P(B) – P(A and B) For mutually exclusive events A and B, P(A and B) = 0 P(A or B) = 1/2 + 1/3 – 0 P(A or B) = 5/6 Ans.5/6...........

If A and B are two mutually exclusive events such that P(A) = (1/2) and P(B) = (1/3), find P(A or B).

Answer»

P(A) = 1/2, P(B) = 1/3

We know, P(A or B) = P(A) + P(B) – P(A and B)

For mutually exclusive events A and B, P(A and B) = 0

P(A or B) = 1/2 + 1/3 – 0

P(A or B) = 5/6

Ans.5/6...........
