There is no replacement.
(a) 130/400 * 129/399 * 128/398
This should give you an idea of how to proceed with the remaining problems.

The SUBJECT shouldn't be "college", it should be 'MATH'. How does kay expect to get help when when she doesn't say what subject she needs help in?
Tanya you're slow..
