This is a good way of calculating your chance of hitting a card, say your sitting with Ah5h and your playing heads up against another guy who is short stacked, he makes a raise All-in and you recon he hasnt got anything but a low pair, maybe 4's you can calculate quyickly in your head the chances you have of hitting a ace.
2% per out per card
So to hit an Ace, there are 3 outs in the deck.
Using the above forumula
2% x 3 x 5 = 30%
this is good to use when you are playing real poker and cant cheat with a odds calculator
