If E1 and E2 are two events such that P(E1) = 1/4,
P(E2/E1) =1/2 and P(E1/ E2) = 1/4
P(E2/E1) =1/2 and P(E1/ E2) = 1/4
- then E1 and E2 are independent
- E1 and E2 are exhaustive
- E2 is twice as likely to occur as E1
- Probabilities of the events E1 ∩ E2 , E1 and E2 are in G.P.
Answer
(A) then E 1 and E 2 are independent, (C) E 2 is twice as likely to occur as E 1, (D) Probabilities of the events E 1 ∩ E 2 , E 1 and E 2 are in G.P.
