Question

From past records it is known that 10% of items from a production line are defective. If two items are selected at random, what is the probability that only one is defective?

Answer 1

Answer:

0.2

Explanation:

The Probability distribution is the function which describes the likelihood of possible values assuming a random variable. The 10% of the items from the production line are assumed to be defective. There is a sample selection of 2 items. The probability that one of the item among the selected sample of two items is found defective is 0.2 (2 items sample *10%)
