Answer:

There are 115141000 possible ways.

Explanation:

Since it is a 7 – card pocker hands, then the total number of poker hands will be:


\binom{52}{7}

Also, the total number of hands without figure cards is


\binom{40}{7}

This is because there are 12 cards with figures (4 x J, Q, K).

Therefore, the number of hands with at least one figure will be:


\binom{52}{7} - \binom{40}{7}

And this would be

133784560 – 18643560 = 115141000
