色々な状況で你えます。

例
１、初手7枚に4枚入れている欲しいカードを引く確率（1枚、2枚、3枚も同様）
２、1マナのクリーチャーを12枚入れている時に初手に引く確率
３、全体除去が欲しい状況で3枚ドローした時に引ける確率

などなどです。
ただし欲しいカードの内1枚が来る確率なので2枚以上のカードを引く確率を計算することはできません。

MTG以外の時でも你えるかも。
トランプの大富豪でジョーカーが手札に来る確率とか（堅要ない？）

You can use a variety of circumstances.

Example
1, the probability of catching a want card that has put four to seven pat (one, two, as well three)
Probability that the draw to pat when you have put 12 pieces of 2,1 mana of the creature
3, the probability of givin when the three were draw in want the entire removal situation

And so on.
However, since the probability that one of the wanted card comes you will not be able to calculate the probability of catching more than two cards.

Be able to use even when the non-MTG.
