The number of typing errors made by a typist has a poisson distribution with an average of two errors per page. if more than two errors appear on a given page, the typist must retype the whole page. what is the probability that a randomly selected page does not need to be retyped? (round your answer to three decimal places.)

0.6767

Step-by-step explanation:

Given : Mean = errors  per page

Let X be the number of errors in a particular page.

The formula to calculate the Poisson distribution is given by :_

Now, the probability that a randomly selected page does not need to be retyped is given by :-

Hence, the required probability :- 0.6767

step-by-step explanation:

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base
