Answer:
options number 1 is the answer
Answer:

Step-by-step explanation:
Given
Dimension: 4.75in, 4.75in and 28.5in
<em>[The complete dimension is missing from the question]</em>
Required
Calculate the volume
The volume is calculated as thus:


--- approximated
Answer:
-5
Step-by-step explanation:
-3y = 10 + 5
-3y = 15
y = - 5
Mean number of errors in each page = 0.01
Mean number of errors in 100 pages = 0.01*100=1
It is possible to use the cumulative distribution function (CMF), but the math is a little more complex, involving the gamma-function. Tables and software are available for that purpose.
Thus it is easier to evaluate with a calculator for the individual cases of k=0,1,2 and 3.
The Poisson distribution has a PMF (probability mass function)


with λ = 1

or
P(k<=3)=
0.9810 (to four decimal places)
