Answer:

Given as :

The number of bulb in the box = 600

The number of defective bulb in box = 12

Let The probability that one bulb taken out random is non-defective = p(E)

According to question

As out of 600 bulbs, 12 bulbs are defective

So, The number of non-defective bulb = 600 - 12 = 588

Now, out of 600 bulbs, 1 bulb is chosen in

And favourable case of chosen non-defective =

So, probability =

Or, p(E) =

Or, p(E) =

Hence, The probability that one bulb taken out random is non-defective is . Answer
