विकल्प
`"P"("A" ∪ bar"B") + P(bar"A" ∪ "B")`
`"P"("A" ∩ bar"B") + P(bar"A" ∩ "B")
P(A) + P(B) – P(A ∩ B)
P(A) + P(B) + 2P(A ∩ B)

Let A and B be two events such that `"P"(bar ("A" ∪ "B")) = 1/6, "P"("A" ∩ "B") = 1/4` and `"P"(bar"A") = 1/4`. Then the events A and B are
Three machines E1, E2, E3 in a certain factory produced 50%, 25% and 25%, respectively, of the total daily output of electric tubes. It is known that 4% of the tubes produced one each of machines E1 and E2 are defective, and that 5% of those produced on E3 are defective. If one tube is picked up at random from a day’s production, calculate the probability that it is defective.
