Our football team needs to fill 4 positions. To do this, it has 10 members, of which only 3 are strong enough to play offensive lineman, while all other positions can be played by anyone. In how many ways can we choose a starting lineup consisting of a quarterback, a running back, an offensive lineman, and a wide receiver?

There are 3 choices for offensive lineman, 9 choices for quarterback, 8 choices for running back, and 7 choices for wide receiver.

3 x 9 x 8 x 7  =
