A box contains 10 good articles and 6 defective articles. One item is drawn at random. the probability that it is either good or has a defect, is a. 64/64            b. 49/64            c. 40/64          d. 24/64

Explanation

Total of articles in a box = `10 +6 = 16` articles


The probability of choosing a good article = `10/16`


The probability of choosing a defective article =` 6/16`


Hence, the probability that the chosen book is either good or defective article = `(10/16) + (6/16)`
