Which of the following statements are true?

a. The @RISK contains a number of functions such as RISKNORMAL and RISKDISCRETE that make it easy to generate observations from the most important probability distributions.
b. You can specify any cell or range of cells in your simulation model as output cells.
When you run the simulation, @RISK automatically keeps summary measures (averages, standard deviation, percentiles, and others) from the values generated in these output cells across the replications.
c. @RISK has a special function, RISKSIMTABLE, which allows you to run the same simulation several times, using a different value of some key input variable each time.
d. All of these statements are true.
