An internal study by the technology services department at lahey electronics revealed company employees receive an average of "2.7" non-work-related e-mails per hour. assume the arrival of these e-mails is approximated by the poisson distribution. a. what is the probability linda lahey, company president, received exactly 3 non-work-related e-mails between 4 p. m. and 5 p. m. yesterday

0.2205

Step-by-step explanation:

Given : Technology Services department at Lahey Electronics revealed company employees receive an average of "2.7" non-work-related e-mails per hour.

i.e.

If the arrival of these e-mails is approximated by the Poisson distribution.

Then , the required probability is given by :-

Hence, the probability Linda Lahey, company president, received exactly 3 non-work-related e-mails between 4 P.M. and 5 P.M. yesterday =0.2205

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
