An incoming lot of silicon wafers is to be inspected for defective ones by an engineer in a microchip manufacturing plant. Suppose that in a tray containing 24 wafers 6 are defective. Two wafers are to be selected randomly for inspection. Find the probabilities of the following events. a. Neither is defective. b. At least one of the two is defective. c. Neither is defective, given that at least one is not defective. d. Answer answer the same three questions, assuming this time that only 3 among the 24 wafers are defective.

Each participant in an experiment was given one of three tasks. Let these three tasks be symbolized by A1,A2, A3 . The number of errors each participant made in performing the task was recorded by use of the categories “0 errors,” “1 error,” and “2 or more errors.” Thus, every participant was classified in two ways, by task and by number of errors. The following table shows the probabilities for these joint events for any participant drawn at random. Task Errors A1 A2 A3 Total 0 .05 .02 .13 .20 1 .08 .17 .10 .35 2 or more .20 .15 .10 .45 Total .33 .34 .33 Use these probabilities to find: The marginal probabilities of the task events A1,A2, A3 The marginal probabilities for numbers of errors The conditional probability for zero errors given task A1 The conditional probability for two or more errors given task A2 The conditional probability of task A3 given no errors
