Answer: 990
Step-by-step explanation:
Because the club has 11 members, there are 11 ways to choose the president.
Because 1 person is now the president, there are only 10 people left who are candidates for vice-president. Therefore, there are only 10 ways to choose the vice-president.
Because 1 person is president and another is vice-president, out of those 11 members, there are now only 9 people who can be candidates for secretary. Therefore, there are 9 ways to choose the secretary.
Multiply the ways to choose a president, vice-president, and secretary out of 11 club members, and you get:
11 * 10 * 9 = 990 (ways)
