    We have respectively  20\times 19\times 18 \times 17 \times 16 *possibilities for 1st 2nd 3rd 4th and 5th player. But we don't care of order so  P = \frac{20\times 19\times 18 \times 17 \times 16}{5\times 4\times 3 \times 2 \times 1}

    Yes.

    Alternatively, the answer can be expressed as ^{20} C_5. You might have a button on your 'calc' that lets you 'punch' that in .....
