The expected number of typographical errors on a page of a certain magazine is H 0.30 What is the probability that the next page you · read contains: S a) exactly one typographical error? b) at least one typographical error?
The expected number of typographical errors on a page of a certain magazine is H 0.50. What is the probability that the next page you read contains: OGS a) exactly one typographical error? b) at least one typographical error?
6. The expected number of typographical errors on a page of a certain magazine is H O50. What is the probability that the next page you read contains: 0167T a) exactly one typographical error? b) at least one typographical error?
A writer makes on average one typographical error every page. The writer has landed a 3-page article in an important magazine. If the magazine editor finds any typographical errors, they probably will not ask the writer for any more material. What is the probability that the reporter made no typographical errors for the 3-page article? Use the Poisson distribution and round answer to 4 decimal places.
A typist makes an average of 5 typo errors per page that she types. If the number of errors per each typed page can be modeled according to the Poisson distribution, what is the probability that she will make more than 3 typo errors in the next page?
B1) The random variable Krepresents the number of typing errors per page in a student' dissertation, with the following probability distribution: [SKI: 5 Marks] 00.05 0.30 2 0.40 3 0.15 4 0.10 1) Find the expected number of errors per page. 2) Find the variance and standard deviation of the random variable. 3) Find the following probability: P(X23) (2 Marks) (2 Marks) (1 Marks)
The mean number of errors per page made by a member of the word processing pool for a large company is thought to be 1.8 with the number of errors distributed according to a Poisson distribution. If a page is examined, what is the probability that more than two errors will be observed? The probability that more than two errors will be observed is ___________?
Suppose an author makes on average one typographical error in every 3 pages he writes. If the number of typos in his next, 300-page book follows a Poisson process, what is approximately the probability that there will be more than 115 typos in this book?
1. The following are the values of waiting time of 6 customers of a city bank in minutes 3, 5, 6, 6, 8, 9 Find mean and standard deviations using the formula: 2 n(n-1) 2. You have drawn a card from a fully shuffled deck of 52 ordinary playing cards. Find the probabilities Clot b a. P(King or Red)- b. P (Heart or Queen) C. P (Below 5/not Ace)- d. P (Above&/ not Face)- e. P Red / Face 3....
6. A certain typing agency employs 3 typists. The average number of errors per article is 2.2 when typed by the first typist, 2.7 when typed by the second, and 3.1 when typed by the third. If your article is equally likely to be typed by any of the three typists, approximate the probability that it will have no errors. Again assume that for each typist the number of errors follows a Poisson distribution.
