1. What is the formula for finding a permutation? 2. Find the number of permutations possible using 8 different objects taken 3 at a time. Let's say there are six numbers: 1, 2, 3, 4, 5, 6: 3. How many permutations of the six digits can arise if they are taken three at a time? 4. How many permutations of the six digits can arise if they are taken two at a time
