    100

    Step-by-step explanation:

    Total produced = 5000 bulbs

    Defective bulbs = 5 out of every 250 bulbs produced

    If 5 out of 250 produced bulb is defective

    Then,

    Good bulbs = 250-5

    =245

    If the company produces 5,000 bulbs, how many will be defective?

    Total defective bulbs out of 5000 bulbs produced=

    Total production/250*5

    =5000/250*5

    =20*5

    =100 bulbs

    That is, defective out of 5,000 produced is 100 bulbs

    There is an expected 100 defective lightbulbs

    Step-by-step explanation:

    In this question, we are asked to calculate the number of light bulbs we think will be defective given that there are usually 5 out of 250 defectives in a batch.

    Now, to adequately account for the number of defective lightbulbs, let's calculate the proportion of lightbulbs which are defective. From the question, this is a case of 5 out of 250. Hence, the ratio of defective lightbulbs mathematically is 5/250

    Now we have a batch of 5,000 produced, to know the total number of defectives expected, we simply multiply the ratio of defectives per batch by the total produced.

    Mathematically, this will be;

    5/250 * 5,000 = 100
