The first option – rand.Next(2) executes behind the scenes the following code: and for the second option – rand.NextDouble(): Since the first option contains maxValue validation, multiplication and casting, the second option is probably faster.
Using Stirling’s approximation, you get If you substitute it into $\choose{n}{n/2}$, you should eventually end up with PS. you might want to check my math before you actually use the answer 🙂
A function should never return a reference to a local object/variable since such objects go out of the scope and get destroyed when the function returns. Differently, the function can return a const or non const reference to an object whose scope is not limited by the function context.

Firebug Firebug provides a highly detailed profiling report. It will tell you how long each method invocation takes in a giant (detailed) table. You need to call console.profileEnd () to end your profile block.
