Question

It is known that a box of 600 electric bulbs contains 12 defective bulbs. One bulb is taken out at random from this box. What is the probability that it is a non-defective bulb?

Options:

A .

\frac{588}{600}

B .

\frac{12}{600}

C . 0.94

D . 0.98

Answer: Option A
:
A and D

Number of non-defective bulbs = 600 – 12 = 588
Total number of bulbs = 600
Probability of picking a non-defective bulb $= \frac{Number of non-defective bulbs}{Total number of bulbs}$
Probability of picking a non-defective bulb = $\frac{588}{600}$ = 0.98
