Transcribed Image Text:8. One of the two boxes, box I and box II, was selected at
random and a ball was drawn randomly out of this box.
The ball was found to be red. If the probability that this red
ball was drawn from box II is 1/3, then the correct option(s)
with the possible values of n₁, n2, n3 and n4 is (are)
(1) n₁ = 3, n₂ = 3, n3 = 5, n4 = 15
(2) n₁ = 3, n₂ = 6, n3 = 10, n₁ = 50
(3) n₁ = 8, n₂ = 6, n3 = 5, n4 20
(4) n₁ = 6, n₂ = 12, n3 = 5, n4 = 20
