Question 1 pts
TRUE or FALSE? Simulation can be used to study detailed relations that
might be lost in an analytical or numerical treatment, but it might be very
time consuming/costly.
Correct! True
False
Question 2 pts
TRUE or FALSE? In a single-server queue simulation, if the arrival rate of
customers showing up is many times higher than the service rate of the
single-server, then a queue will not be formed.
True
Correct! False

TRUE or FALSE? Suppose the arrival of clients to a bank can be modeled
as a Poisson process with a given hourly rate . Then the expected
number of clients arriving between 10:00-11:00am is the same as the
expected number of clients arriving between 1:00-2:00pm.
Correct! True
False
Question 4 pts
TRUE or FALSE? If the covariance of and is equal to zero, i.e.
, then and must be independent.
True
Correct! False

TRUE or FALSE? Suppose I toss two fair dice. The events "sum is less or
equal than 2" and "sum is greater than 11" are independent.

Question 6 pts
A pack contains 4 blue, 2 red, and 2 green pens. Suppose a pen is drawn
at random from the pack, is replaced, and then the process repeated one
more time (for a total of two draws). What is the probability of first drawing
a blue pen and then a green pen?
a. 2/7
b. 1/4
c.1/2
Correct! d. 1/8
e. 3/4
Question 7 pts
Again, suppose a pack contains 4 blue, 2 red and 2 green pens. A pen is
drawn at random from the pack, but this time the pen is not replaced, and
then the process is repeated one more time (for a total of two draws).
What is the probability of first drawing a blue pen and then a red pen?
a. 3/4
b. 4/7
c. 11/14
d. 2/7
Correct! e. 1/7
