Q3 of 31 Page 1

Out of 200 bulbs in a box, 12 bulbs are defective. One bulb is taken out at random from the box. What is the probability that the drawn bulb is not defective?

Given


Total number of bulbs = 200


Number of defective bulbs = 12


Number of non-defective bulbs = 200 – 12 = 188


We know,


Probability of an event


⇒ Probability of getting a non-defective bulb
