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.
2. A newspaper finds that the mean number of typographical errors per page is four. Find the probability that: 2. a) exactly three typos are found on a page. b) at most three typos are found on a page.
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 ___________?
If the number of typopgraphical errors per page follows a Poisson distribution with mean 3, what is the probability that the total number of errors in 8 randomly selected pages is 10?
A typist makes an average of 4 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? Express your answer in decimals and round to two significant places after the decimal. For example 0.1678 should be entered as 0.17.
