We have 11 different members we can choose from, and we want to count the number of committes consisting of 4 members. To solve this sort of problem, we use combinations:
`11C4 = ((11),(4)) = (11!) / (4!7!) = 330`
Therefore there are 330 ways Coca-Cola can form an ethics subcommitte of four members from the 11 member board of directors.
