The chances of defective screws in three boxes A, B, C are respectively. A box 5 6 7 is selected at random and a screw drawn from it at random is found to be defective. Then, the probability that it came from box A, is
D.
Let E1, E2 and E3 denote the events of selecting boxes A, B, C respectively and A be the event that a screw selected at random is defective.
Then,
Now, by Baye's rule, the required probability

1 sq unit
4 sq unit
None of these
The degree of the differential equation of all curves having normal of constant length c is
