Discussion:
Q: Suppose you are playing Texas holdem and you hold the 8 and 9 of hearts. The flop comes the 3 of hearts, the jack of spades and the Queen of hearts. You now have an inside straight draw (needing a 10 for a straight) and a flush draw (needing a heart for a flush).
a) What is the probability that you hit a straight or a flush on the turn?
b) What is the probability that you hit a flush or a straight on either the turn or the river?
