Question 469239
N is the set of possible straight-flushes in hearts.
We are assuming all cards are hearts.
For the hand to be a straight all cards must be in consecutive order.
A-2-3-4-5
This is the lowest possible straight, the highest possible straight would yield a royal flush
10-J-Q-K-A
The number of cards from A to 10 is 10 cards
Therefore there are only 10 possible straights with 5 hearts.
10 outcomes in N
