Скачать или смотреть Counting and its Value to Computing (Multiplication Principle)

Many areas of computing rely on our ability to count the number of possible outcomes or conditions. We use counting to determine the best way to structure our code, predict performance of our applications, identify the probability of certain events, or evaluate the effectiveness of our security. The most basic of these is the multiplication principle of counting.
