Let X is a random variable shows the number of defective out of 10. Here X has hypergeometric distribution with following parameters :
Population size: N = 24
Sample size: n= 10
Number of defectives in sample: k = 2
The probability that both defective smartphones will be selected and put on display is
Suppose a packing box contains 24 smartphones, of which two phones are defective. If, while setting...
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.
2. (4 points) A box contains 5 batteries. Two of the batteries in the box are defective. An inspector selects two of the batteries at random from the box and tests the selected batteries to determine if they are defective. The box will be rejected if both of the sampled batteries are defective. What is the probability that the inspector will reject the box?
Paragraph 2-114. A lot of 100 semiconductor chips contains 10 that are defective. (a) Two are selected, at random, without replacement, from the lot. Determine the probability that the second chip selected is defective (b) Three are selêcted, at random, without replacement, from the lot. Determine the probability that all are defective.
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?
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...
A box contains 30 parts, of which 5 are defective and 25 are non-defective. If two parts are selected without replacement a.Construct a tree diagram with a listing of all the outcomes and probabilities: b.P(exactly one non-defective part) include both fractional and decimal answers. c.P( at least one defective) d.P( neither is defective)
In a production facility ., a batch of three hundred products contains eight that are defective. Two are selected from batch, at random, without replacement * What is the probability that the second one selected is defective given that the firstone was defective? *What is the probability that both are def ective? *What is the probability that both are acceptable?
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 batch of 536 containers for frozen orange juice contains 6 that are defective. Two are selected, at random, without replacement from the batch. a) What is the probability that the second one selected is defective given that the first one was defective? Round your answer to five decimal places (e.g. 98.76543). b) What is the probability that both are defective? Round your answer to seven decimal places (e.g. 98.7654321). c) What is the probability that both are acceptable? Round...
QUESTIONS A box contains 140 USB drives, 38 of which are defective. Consider drawing a non-defective USB drive to be a "success." If 25 USB drives are randomly selected without replacement, the results do not form a binomial distribution for which reason(s)? (select all that apply) The probability of success is not the same in each trial. The trials are dependent. Each trial has more than 2 possible outcomes. There is not a fixed number of trials.
