Many believe that playing card games are all about luck and practice. Well, that might not be entirely true. It is quite accurate that you need both practice and luck, but those are not the only factors that contribute to your victory. Most of it is logic and mathematics, and the winning concoction is a proportionate mix of all the abovementioned factors. Believe it or not, math textbooks now have many problems with playing cards and finding various probabilities, making learning easier for kids of this day and age. Not only do you have the upper hand if you are good with mathematics, but it will also let you calculate your opponent's gameplay, ultimately paving a victorious path for you (with the right amount of luck, of course). This post will tell you about the probability of getting a spade face card. Before that, let's brief you on the basics of a deck of cards that includes spade face cards.

A regular deck of 52 cards is divided into 4 suites, each with 13 cards. The four suites are namely hearts, clubs, diamonds, and spades. Each suite has ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, jack, queen, and king. These are the most common packs of playing cards today. Face cards are ideally the cards in a deck with pictures or figures (that is, they have a face depicted in them).
Hence the face cards are king, queen, and jack, all of which have faces shown on them. The rules and different nooks of these playing cards are well known, but people rarely question the whole system and numbering of the cards. Fun fact, the four suits in the deck are supposed to represent the four seasons we experience, the 52 cards signify the 52 weeks in a year, and the thirteen cards present in a suite is said to represent the thirteen lunar cycles we go through.
Making a callback to the mathematics part of playing cards, the probability of drawing any random card out of the deck is 1/52. The probability of drawing any of the four suites is calculated to be 13/52, which can be simplified as ¼, a much greater fraction than the initial probability of 1/52. Each suite has 3 face cards, meaning there are 12 face cards in the whole 52 cards in the deck. Now, drawing a face card out of the bunch would be a probability of 12/52.

The formula for the conditional probability of event A happening given that its known event B already happened is given by the formula:
P(A∣B) = P(A∩B)/ P(B)
Let's take A to be = "Drawing a face card" and B = to be "Drawing a spade." We can calculate this probability by finding two values: P(A∩B), or the probability of drawing a face card which also happens to be a spade card, and P(B), or the probability of drawing a spade from a deck of cards.
Since there are three face cards in total in the deck (Jack, Queen, and King) or particularly in the spades suit, and 52 total possible cards, the P(A∩B) = 3/52; in a similar sense, we also know that there are 13 spades in a deck of 52 cards, so P(B) = 13/52, which can be simplified to be ¼.
P(A∣B) = P(A∩B)/ P(B) = (3/52) (13/52) = 3/13
Therefore, it can be positively concluded that the probability of drawing a spade face card is 3/13. Alternatively, if one had to do this computation, one could take hold of the number of face cards in the spade cards. Knowing that there are only 13 spade cards, of which 3 are spade face cards, the probability can be calculated as 3/13.
Now that you know the probability of getting a spade face card, you can use this knowledge to determine the odds of flopping a spade face card in a real game and strategize accordingly. To practice and play poker online, download the GetMega app and register for various contests.
