2. Answer:

   ans is (i) = 6/25 ,(ii)= 19/25

   Step-by-step explanation:

   no.of items n(E)=500

   no of defective n(D)=120

   no of non defective n(N)=500-120=380

   we know that,

   (i) The probability of defective= n(D)/n(E)=120/500=6/25

   (ii) the probability of non defective= n(N)/n(E)=380/500=19/25

   hope it helps you....
