Answer:

  • 303600

Step-by-step explanation:

There are:

  • 30 seniors, 38 juniors, 24 sophomores, and 18 freshmen

The president must be a senior.

  • Number of ways = 30

The assistant must not be a freshman.

  • Number of ways = 30 + 38 + 24 = 92

The accountant can be anyone.

  • Number of ways = sum of all = 110

Number of ways to pick officers:

  • 30*92*110 = 303600
