Hello,
Please I have this question and would be pleased if someone can helpe me out.
A quality control procedure requires that 6 items are selected from every box of components supplied to a company. A box contains 25 items, 5 of which the supplier knows to be defective.
(i) How many different samples can be selected from the box?
(ii) How many of these will contain no defective items.
(iii) How many samples will contain more than 2 defective items?

Thank you.
