Question

It is known that a box of 800 electric bulbs contains 36 defective bulbs.One bulb is taken at random out of the box. What is the probability that the bulb chosen is nondefective?

Can anyone tell me the answer please?

Answer 1

Answer:

Step-by-step explanation:

Total bulbs=800

Defective bulbs=36

Non defective bulbs=800-36=764

Probability of picking a non defective bulb =(no. of non defective bulb)/(total no. of bulbs)

=764/800=191/200

Answer 2

Answer:

Correct answer is 764 by 800
