When a machine is adjusted properly, 60% of the items produced by it are of high quality and the other 40% are of medium quality. However, the machine is improperly adjusted, 25% of the items produced by it are of high quality and 75% are of medium quality. The machine is improperly adjusted 10% of the time. Suppose that 4 items produced by the machine at a certain time are randomly selected and inspected. If 3 of these iterms are...
When a particular machine is functioning properly, 75% of the items produced are non-defective. If eight items are examined, what is the probability that one is defective? If eight items are examined, what is the probability that exactly three are non-defective? If eight items are examined, what is the probability that at least 6 are non-defective?
suppose that our concern is with an inspection process where the objective is to inspect machine parts let Ai denote the event that part selected at time it is defective also let X denote the number of parts inspected until a defective part is found and let p denote the probability that a randomly selected part is defective if parts are independent of each other what is P(X=i) ? What distribution describe the random variable X?
1. (a) A committee of 6 people is to be chosen at random in a Club which has a membership of 20 men and 30 women. What is the probability that 6 marks 6 marks 8 marks] (b) In a factory there are three machines which produce bolts. Machine A pro- duces 50% of the bolts and of these 2% are faulty. Machine B produces 20% of the bolts and of these 1.5% are faulty, and Machine C produces 30%...
The weight of items produced by a machine is normally distributed with a mean of 8 ounces and a standard deviation of 2 ounces. Refer to Exhibit 6-5. What is the probability that a randomly selected item will weigh more than 12 ounces? The Probability is
Suppose that when a machine is adjusted properly, 83% of the items produced by it are of high quality and the others are of medium quality. Suppose, however, that the machine is improperly adjusted during 17% of the time and that under these conditions 14% of the items produced by it are of high quality and the remaining are of medium quality. If an item is selected at random and found to be of high quality, what is the probability...

Judging from recent experience, 4% of the computer keyboards produced by an automatic, high-speed machine are defective. If 10 keyboards are randomly selected, what is the probability that exactly 1 of the keyboards are defective? O 942 665 O 052
A machine that manufactures automobile parts produces defective parts 13% of the time. If 10 parts produced by this machine are randomly selected, what is the probability that at least 2 of the parts are defective? Carry your intermediate computations to at least four decimal places, and round your answer to at least two decimal places.
Exhibit 6-5 The weight of items produced by a machine is normally distributed with a mean of 8 ounces and a standard deviation of 2 ounces. Refer to Exhibit 6-5. What is the probability that a randomly selected item will weigh more than 10 ounces?
