There are 11 widgets in box. 4 of them are defective and 7 of them are non-defective. Five widgets from the box are selected at random. a) What is the probability that exactly 2 parts will be defective, assuming no replacement after each selection? b) What is the probability that 1 sample widget selected will be defective, assuming no replacement after each selection?
In a box of 11 parts, four of the parts are defective. Two parts are selected at random without replacement. Find the probability that both parts are defective.
Box I contains 4 defective and 8 non-defective products, whereas box II contains 5 defective and 5 non-defective products. An item is randomly chosen from box I and put into box II, and an item is then randomly selected from box II. a) the probability that the product selected from box II is defective is ? b) the conditional probability that the transferred item was defective, given that a defective item is selected from box II is?
we have four boxes. box #1 contains 2000 components of which 100 are defective. Box #2 contains 500 components of which 200 are defective. boxes #3 and #4 each contain 1000 components with 100 of them being defective. a box is selected by ruling a fair four sided die and then a single item is randomly chosen from the box. a.What is the probability that the selected component is defective? b. if the selected item is defective, find the probability...
A shipment of 40 parts contains 12 defective parts. Suppose 3 parts are selected at random, without replacement, from the shipment. What is the probability that exactly 2 parts are not defective?
A shipment of 40 parts contains 12 defective parts. Suppose 3 parts are selected at random from the shipment. What is the probability that all 3 parts are defective?

A lot of 108 semiconductor chips contains 20 that are defective. Two are selected randomly, without replacement, from the lot. Round your answers to three decimal places (e.g. 98.765) a) What is the probability that the first one selected is defective? b) What is the probability that the second one selected is defective given that the first one was defective? c) What is the probability that both are defective? d) How does the answer to part (b) change (give the...

Five percent (0.05) of the parts produced by a machine are defective. Twenty(20) parts are selected at random for study. A. what is the probability that more than 4 parts are defective? B. what is the probability that exactly 3 parts are defective? C. what is the expected number of defective parts in the sample? D. What is the variance and standard deviation of defective parts in the sample?
