Answer 2

Out of 600 electric bulbs one bulb can be chosen in 600 ways

⇒Total number of outcomes = 600

Number of non-defective bulbs = 600 -12

= 588

⇒ Number of favourable outcomes = 588

P(Getting a non-defective bulb) = No. of favourable outcomes÷Total no. of outcomes

⇒ Probability = 588/600

Hence, the probability of getting a non-defective bulb = 0.98
