Question

If E1 and E2 are two event associated with random experiment such that P(E2) = 0.35,P(E1 or E2 ) = 0.85 and P ( E1 and E2 ) = 0.15,Find P(E1).

Answer 1

Let P(E1) = x .

Then

P ( E1 or E2 ) = P (E1 ) + P (E2) -- P ( E1 and E2)

=> 0.85 = x + 0.35 - 0.15

=> x ( 0.85 -- 0.35 + 0.15 ) = 0.65

Hence

P(E1) = 0.65.
