Components of a certain type are shipped to a supplier in batches of ten. Suppose that 48% of all such batches contain no defective components, 27% contain one defective component, and 25% contain two defective components. Two components from a batch are randomly selected and tested. What are the probabilities associated with 0, 1, and 2 defective components being in the batch under each of the following conditions? (a) Neither tested component is defective.
(b) One of the two tested components is defective. [Hint: Draw a tree diagram with three first-generation branches for the three different types of batches].
