Solution

The correct option is A

6464


Let A be the event of drawing one good article whereas B be the event of drawing one defected article.

Here, P(A)=1010+6=1016

and P(B)=610+6=616

The events A and B are mutually exclusive. Thus, the required probability is P(AB)=P(A)+P(B)

P(AB)=1016+616=1616=1

Hence, the correct option is (a)
