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 reasons select all that apply. a. There is not a fixed number of trials. b. The probability of success is not the same in each trial. c. each trial has more than two possible outcomes. d. The trials are dependent...

10 point A box contains three defective and seven non defective chips. Three chips are drawn randomly without replacement one after the other. Let X be the # of defective chips. Using hyper geometric model construct the probability distribution of X and show that it fulfills the two conditions of probability distribution. Also find E(X) 1 Add file Page 2 Back Submit LALAR

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.

9. The four conditions required for using a Binomial distribution are. (a) A fixed number of trials (n). b) On each trial, there are two possible outcomes, one of which we call a "success" (c) On each trial, P(success) is the same (d) The outcomes of each trial are independent For each of the following decide if the random variable defined (X) is a Binomial variable or not. If it is not a Binomial variable, say which of the four...

Ten cards are in a box, 5 red and 5 blue. Three cards are drawn without replacement. Let X be the number of red cards drawn. Yes A fixed number of trials are conducted. If Yes - then n=. No There are 2 possible outcomes for each trial Yes No Yes The probability of success is the same on each trial. No The trials are independent or the sample is less than 5% of the population. Yes No The random...

One coin is weighted so that the probability that it lands tails up is 25%. Another coin is weighted so that the probability that it lands tails up is 85%. If each coin is tossed 5 times and the total number of tails is recorded, the results will not form a binomial distribution for which reason(s)? (select all that apply) Each trial has more than 2 possible outcomes. The trials are dependent There is not a fixed number of trials....

Suppose a packing box contains 24 smartphones, of which two phones are defective. If, while setting up a store display, a salesclerk selects 10 smartphones at random from the box without replacement, what is the probability that both defective smartphones will be selected and put on display?

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...

Determine whether the given procedure results in a binomial distribution (or a distribution that can be treated as binomial). If the procedure is not binomial, identify at least one requirement that is not satisfied. Six different senators from the current U.S. Congress are randomly selected without replacement and whether or not they've served over 2 terms is recorded. Does the probability experiment represent a binomial experiment? A. Yes, because the experiment satisfies all the criteria for a binomial experiment. B....
