# 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 - Mathematics

Short Note

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.

#### Solution

Total number of possible outcomes = 200

Number of non-defective bulbs = 200 − 16 = 184

∴ P(getting a non-defective bulb)  = 184/200 = 23/25
