I ' ll actually contribute to this one . This one , I just learned today . In my spare time , I design tabletop games . In order to make better games , I ' ve decided to study probability . Something you probably didn ' t notice before , but is kind of awesome . Math nerds , take point . A deck of 52 playing cards has four suits . In a suit , there is one Ace , nine number cards , 2 10 and three face cards . 1 Ace 3 Face 9 Numbers 3 Ace 3 Face 3 NumbersThis means the probability of drawing any one card from one of these card types scales exponentially . If you added 27 more cards to each suit , you ' d have 3 as well . Bonus Adding a fourth card type would make the deck 160 cards . <| sep |> If you really feel the need to shoot at a plane with small arms , aim for the engines or wings , much more effective .
