Question

500 articles were selected at random out of a batch containing 10000 articles and 30 were found defective. how many defective articles would you reasonably expect to find in the whole batch?

Answer 1

500 ............because probability of getting each article defective is equal.

Answer 2

Answer:

Number of defective articles expected = 600

Step-by-step explanation:

Total number of articles = 10000

Number of samples = 500

Number of defects = 30

Number of samples from the total number of articles = $\frac{10000}{500}$ = 20

Number of defects expected in each sample batch = 20 x 30

Therefore, the number of defects expected = 600.
