A lot contains 50 defective and 50 non-defective bulls. Two bulbs are drawn at random, one at a time, with replacement. The events A,B,C are defined as : A=(the first bulb is defective ) B= (the second bulb is non-defective) C=(the two bulbs are both defective or both non-defective). Determine whether (i) A,B,C are pairwise independent. (ii) A,B, C are independent.

A lot contains equal number of defective and non defective bulbs. Two bulbs ar drawn at random, one at a time, with replacement.
