#### Answer:

2 or 4 ways, depending on whether or not the buses are numbered.

#### Explanation:

The best way to do this, at least for me, is to list all the possibilities.

Bus, Bus

4, 7

5, 6

There are only two ways to do it if you don't care about the order of buses.

Bus 1, Bus 2

4, 7

5, 6

6, 5

7, 4

There are 4 ways if you number the buses.
