Question

11. How many different ways can the 16 numbered pool balls be placed in a line on the pool table?

Answer 1

The number of ways are 16! or 20,922,789,888,000.

Explanation:

Consider the provided information.

We need to determine the number of different ways 16 numbered pool balls be placed in a line on the pool table.

For the first place we have 16 balls.

For the second place we have 15 balls left.

Similarly for the third place we have 14 balls as two balls are already arranged and so on.

Or we can say that this is the permutation of 16 things taking 16 at a time.

Thus the number of ways are:
`16!` or
`^(16)P_(16)`

`16!=16*15*14*13......*2*1=20,922,789,888,000`

Hence, the number of ways are 16! or 20,922,789,888,000.
