Calculate Offices Selection: Calculate the number of ways to choose a president, vice-president, secretary, and treasurer from 16 people, where each person can hold only one office. Use the permutation formula since the order in which the offices are filled matters.Calculation: 16×15×14×13=43,680
Rank Top Salespeople: Calculate the number of ways to rank the top 5 salespeople from a group of 37. Use the permutation formula because the order of ranking is important.Calculation: 37×36×35×34×33=45,297,120
