​GivenP(A) = 3/5 and P(B) =1/5 . Find P(A or B), if A and B are mutually exclusive events. ​

Question

GivenP(A) = \(\frac{3}{5}\) and P(B) = \(\frac{1}{5}\). Find P(A or B), if A and B are mutually exclusive events.

Answer 1

Here; P(A) = \(\frac{3}{5}\) and P(B) = \(\frac{1}{5}\)

Since A and B mutually exclusive events

P(A ∪ B) = P(A) + P(B)

\(\frac{3}{5} + \frac{1}{5} = \frac{4}{5}\)
