Monte Carlo: Basics
Consider now the tossing of N independent fair coins.
Monte Carlo: Basics
For each coin there are two possible (equally likely) outcomes.
Monte Carlo: Basics
Therefore, for N coins there are 2N possible (equally likely) outcomes.
Monte Carlo: Basics
For the N -coin-tossing experiment each outcome is a distinct string of H and T , the string length being N .
Monte Carlo: Basics
The probability for each outcome (string) in the throw of N coins is thus 2−N .
