The number of typing errors made by a typist has a Poisson distribution with an average of seven errors per page. If more than seven 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?

0.599  is the probability that a randomly selected page does not need to be retyped.

Step-by-step explanation:

We are given the following in the question:

The number of typing errors made by a typist has a Poisson distribution.

The probability is given by:

We have to find the probability that a  randomly selected page does not need to be retyped

P(less than or equal to 7 mistakes in a page)

Thus, 0.599  is the probability that a randomly selected page does not need to be retyped.

answer: get jesus in your life

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
