Explain in brief the functions of Crystal Ball

What will be an ideal response?

A very useful feature of Crystal Ball is the ability to use its functions within Excel. A complete list may be found by clicking the Insert Function button (fx) on the Excel menu bar and selecting the Crystal Ball category. The random variate generation functions (CB. uniform, CB.normal, CB.exponential, and so on) may be used in a spreadsheet model instead of defining an assumption in the usual way. These functions are often useful to embed within complex Excel formulas.
