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 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 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
A box contains 12 connectors, 9 good and 3 defective. What is the probability of obtaining exactly 2 good and 1 defective connector in drawing 3 parts from the box without replacement?
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?
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.
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?
1.) Suppose that a box contains 8 cameras and that 3 of them are defective. A sample of 2 cameras is selected at random. Define the random variable X as the number of defective cameras in the sample. Hint: Make a probability tree for selecting 2 cameras without replacement. Write the probability distribution for X. k P(X=k) What is the expected value of X? 2.) Assume that a procedure yields a binomial distribution with a trial repeated n=5n=5 times. Find...
7) A lot of 100 semiconductor chips contains 20 that are defective. Two chips are selected at random, without replacement, from the lot. (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?
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
