Worksheet: Fundamental Counting Principle
In this worksheet, we will practice finding the number of all possible outcomes in a sample space using the Fundamental Counting Principle.
A code breaker is trying to find the value of an eight digit number. The figure below shows the digits that he has already discovered. He has narrowed down his options for the digit represented by the letter to the following set of numbers . Given that he currently knows nothing about the other digits, how many possible numbers does he have left to try?
