a package contains 12 resistors, 3 of which are defective. if 5 are selected find the probability of getting the following results 1 defective
N = 12
k = 3
n = 5
P(1 defective) = 3C1 * 9C4 / 12C5 = 3 * 126 / 792 = 0.4773

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 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 50 parts contains 12 defective parts. Suppose 3 parts are selected at random, without replacement, from the shipment. What is the probability that at least one part is defective? 0.5696 0.5610 0.1435 0.0427
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?
A box of 8 flashbulbs contains 3 defective bulbs. A random sample of 2 is selected and tested. Let X be the random variable associated with the number of defective bulbs in a sample. (A) Find the probability distribution of X. (B) Find the expected number of defective bulbs in a sample.
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...
Huur wicarea probability A bin contains 60 light bulbs of which 5 are defective. If 4 light bulbs are randomly selected from the bin with replacement, find the probability that all the bulbs selected are good ones. Round to the nearest thousandth if necessary
A lot of 99 semiconductor chips contains 19 that are defective. (a) Two are selected, one at a time and without replacement from the lot. Determine the probability that the second one is defective. (b) Three are selected, one at a time and without replacement. Find the probability that the first one is defective and the third one is not defective.

3. Suppose a batch of 50 items contains 4 defective ones, and a sample of 5 items is selected at random from the batch. Let X denote the number of defective items in the sample. (a) What is the name of the distribution of X? (b) Find the probability mass function for X. You may write this as a function or as a chart. If you write it as a function, also give the set of X values where the...
