Hey!
Number of defective bulbs = 12
Hence, number of bulbs not defective
=600-12
=588
The probability of getting a non defective bulb is 588/600 = 0.98
Hope this helps!

Answer:
Step-by-step explanation:
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) = 50
⇒ Probability 51
Hence, the probability of getting a non-defective bulb = 0.98
