Answer:
Step-by-step explanation:
Total number of outcomes= 12
Total number of defective items= 4
If 3 items are drawn at random, the probability of them not being defective will be:-
12-4= 8
8/12= 2/3
Therefore, there will be a 2/3 chance that the items are NOT defective.
There will also be a 1/3 chance that the items are defective.
