Answer:

Part I

p(x=1)=0.0000

p(x=2)=0.0000

Part II

p(x)=0.11

Step-by-step explanation:

For Poisson distribution:

$p(X=x)=e^-m\frac{m^x}{x!}$

Where m=mean, x=number of events

Given x=1, and mean,m=28

$p(X=1)=\frac{e^{-28} *28^1}{1!}\\p(X=1)=0.0000$

For x=2 and mean,m=28

$p(X=2)=\frac{e^{-28} *28^2}{2!}\\p(X=2)=0.0000$

For Uniform Distribution

Time interval 10 and 19 minutes is 9

Time interval between 15 and 16 minutes is 1

Therefore:-

$p(x)=\frac{1}{9}\\p(x)=0.1111\\p(x)=0.11 \ (2d.p)$

antiseptic1488 [7]

This is the concept algebra.
Volume of of paint that is required to paint large shipping crate is a liters.
suppose the volume of this crate is x cubic units.
The volume of the next crate to be painted will be 2x cubic units.
Hence the amount of paint required to paint the crate will be:
(volume of bigger crate)/(volume of smaller crate)×(volume of liters required to paint the first crate)
=(2x)/(x)×a
=2a liters
To paint the new crate 2a liters of oil is needed.
