In a box containing 15 identical bulbs, 5 are defective. If 5 bulbs are drawn at random from the box with replacement, find the probability that (i) none is defective (ii) only one of them is defective (iii) atleast one of them is defective

In a box containing 15 bulbs, 5 are defective. If 5 bulbs are selected at random from the box, find the probability of the event, that (i) None of them is defective (ii) Only one of them is defective. (iii) Atleast one of them is defective.
