probability of a defective bulb

The probability of randomly selecting the defective bulb from a box of 100 bulbs with one defective bulb is 1/100. The correct answer to the question is option 1) 1/100. The probability that a bulb taken out is defective from a box of 100 where one is known to be defective is simply the ratio of defective bulbs to the total number of bulbs. Answer: The probability that at most 3 bulbs are defective in a box of 100 bulbs is 0.8506 or approximately 85.06%..

Probability of a Defective Bulb: (a) To find the probability that the bulb drawn is defective, we use the ratio of the number of defective bulbs to the total number of bulbs. Since there are 10 defective bulbs out of 100, the probability P(defective) is 10/100, which simplifies to 0.10 or 10%. Probability of a Non-Defective Bulb: (2) The probability that one of the bulbs to be drawn will be defective and the other will not be defective is 7/15 --> also sufficient, but a little bit trickier: if it were 3 defective and 7 good bulbs OR 7 defective and 3 good bulbs, then the probability of drawing one defective and one good bulb would be the same for both cases (symmetric .Consider three boxes containing a brand of light bulbs.

Box 1 contains 1000 light bulbs of which 10% are defective. Box 2 contains 2000 light bulbs of which 5% are defective. Suppose a box is given to you at random and you randomly select a light bulb from the box. If that light bulb is defective, what is the ; Box 1 contains 200 bulbs and Box 2 contains 100 bulbs. Each box has 20 defective bulbs. The probability of randomly selecting a non-defective bulb from a box with 600 bulbs, of which 12 are defective, is 49/50. Explanation: When calculating the probability of getting a non-defective bulb from a box containing both defective and non-defective bulbs, we need to look at the ratio of non-defective bulbs to the total number of bulbs.
