Excellent idea. We will implement it. :wink:
Thanks Brooding Silver.
The formula to find the probability of drawing a hand (H) with a particular card or cards (X) out of a certain deck size (D) when there are (Y) of that card in the deck is:
P(X,(H-X)) = (C(Y,X) x C(D-Y,H-X)) / C(D,H)
So if we have a deck of forty cards with seventeen lands in them and we want to know our chance to draw two lands in our opening draw of seven cards (not less or more - only two), then our formula would look like:
P(2,5) = (C(17,2) x C(23,5)) / C(40,7)
P(2,5) = 24.6% chance of drawing only two land in the opening draw.
Tell me what C(X, Y) stans for. Combination?
