प्रश्न
It is known that a box of 200 electric bulbs contains 16 defective bulbs. One bulb is taken out at random from the box. What is the probability that the bulb drawn is non-defective.
उत्तर
Total number of possible outcomes = 200
Number of non-defective bulbs = 200 − 16 = 184
∴ P(getting a non-defective bulb) = `184/200 = 23/25`
