Write and run a simulation to estimate the probability of getting five cards of the same suit (**a flush, a straight flush or a royal flush**) in a draw of seven cards. A flush consists of five cards all of the same suit (K 10 7 6 4). A straight flush is a hand containing five cards of sequential rank, all of the same suit (5 4 3 2 A). Ace can be treated as 1 or as above a K for the purposes of a straight (10 J Q K A is a royal flush). Note that because you draw seven cards, it is possible to also get six or seven cards of the same suit - and they will be considered a flush as well.
