3 out of every 1,000 bulbs produced are defective. If 5,000 bulbs are produced, how many would you expect to be defective
Cross multiply and solve for x.
3/1000 = x/5000
3 x 5 = 15
15000
To calculate the number of defective bulbs, we first need to find the proportion of defective bulbs out of the total number of bulbs produced.
The given information states that for every 1,000 bulbs, 3 are defective. So, the proportion of defective bulbs is 3/1,000 = 0.003.
To find out how many bulbs would be expected to be defective out of 5,000 bulbs, we multiply the total number of bulbs by the proportion of defective bulbs:
Number of defective bulbs = 5,000 * 0.003 = 15.
Therefore, you would expect 15 bulbs to be defective out of the 5,000 produced.
