Q. 225.0( 1 Vote )

A box contains 10

Answer :

As total articles = 10 + 6 = 16


P(good) =P(G) = 10/16


And P(defective)= P(D) = 6/16


As there it is not possible to select an item that is both good and defective.


P(good or Defective) = P(G D) = P(G) + P(D) = 16/16 = 1


As our answer does not directly seems to match with any option.


But option (a) is 64/64 = 1


option (a) is the only correct choice.
