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?
probability that all 3 parts are defective =P(first defective)*P(second defective|first defective)*P(third defective|first two defective)=(12/40)*(11/39)*(10/38)=0.0223

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
A shipment of 60 parts contains 9 defective parts. Suppose 3 parts are selected at random, without replacement, from the shipment. What is the probability that at most one part is not defective? Options: 0.9439 0.0887 0.0561 0.0296
Suppose a shipment of 50 baseballs contains 3 that are defective. Baseballs from the shipment are randomly selected one at a time and checked for defects. If a baseball is found to be defective it is placed in a bin for return and reimbursement, if it is good it is put aside for use. Determine the probability that the 3th defective baseball is identified on the 10th sample.
Suppose a shipment of 130 electronic components contains 3 defective components. To determine whether the shipment should be accepted, a quality-control engineer randomly selects 3 of the components and tests them. If 1 or more of the components is defective, the shipment is rejected. What is the probability that the shipment is rejected?
a bin of 50 parts contains five that are defective. a sample of three parts is selected at random without placement. a. determine the probability that at least two parts in the sample are defective. b. given that at least two parts in the sample are defective, what is the probability that all three are defective
Problem 3: A shipment of 250 computers contains eight computers with defective CPUs. A sample without replacement of size 20 is selected. Let X be a random variable that denotes the number of computers with defective CPUs. Find the mean and variance of the random variable X.
Suppose you just received a shipment of 14 televisions 3 of the televisions are defective it to televisions are randomly selected compute the probability that both televisions work what is the probability at least one of the televisions does not work
) Suppose that the proportion θ of defective items in a large shipment is unknown, and the prior distribution of θ is a Beta distribution with α = 5 and β = 10. Suppose also that 20 items are selected at random from the shipment, and that exactly one of these items is found to be defective. If the squared loss function is used, what is the Bayes estimate of θ? Hint: Estimator is a function of observations, while estimate...
A bin of 50 parts contains 5 that are defective. A sample of 10 parts is selected at random, without replacement. (a) How many different samples of size 10 are there that contain at least three defective parts? (b) How many ways to obtain a sample of 10 parts from the bin of 50? (c) What is the probability of obtaining at least three defectives in a sample of 10 parts?
