If a school has lockers with
50 numbers on each combination
lock, how many possible
combinations using three
numbers are there.

    how about 50*50*50?

    Naturally, the sequential numbers in the combination cannot be too close together, because of the physical mechanisms of the lock, but in theory all sequences of three of the 50 numbers are possible.

    450
