The Probability of Getting a Four-of-a-Kind Poker Hand
Because of its rareness, a four-of-a-kind card combination is one of the most aspired and dreamt about hand in poker. It is essentially made up of four cards all having the same value and an individual card. Together they form one of the most potent hands in the game. This hand is almost unbeatable by almost all the other card combinations in the poker hand rankings except for a couple of very special hands.
A four-of-a-kind can only be beaten by two special card combinations. The straight flush and the royal flush are the only hands that can put away this pretty potent hand. A straight flush is basically made up of five cards under a single suit. They can also be arranged in sequential order. Meanwhile, a royal flush is just like a straight flush. The only difference is that the royal flush is made up of all face cards.
Aside from these two, all the other poker hands succumb to the strength and power of a four-of-a-kind. This hand is almost unbeatable when played on any situation. The no pair/high card, one pair, and two pair card combinations are simply helpless against it. The three-of-a-kind, straight, and flush are just as powerless over it. Even a full house is limited against the strength of a four-of-a-kind.
According to some mathematical calculations, the frequency of getting this hand is very low already. The total number of card combinations that could contain a four-of-a-kind is 624. Because of this ultra low frequency, the probability of getting such a strong hand falls as well. It is measured at the contemptibly small rate of 0.024 percent.
Upon analyzing the probabilities of each and every poker hand, it can be observed that the probability of getting these card combinations decreases as their value increase. Simultaneously, the probability of getting these poker hands increases as their values submerge. These are dominant trends that are usually observed when checking and analyzing the different probabilities of each and every hand in poker.
The opposite relationship between poker hand value and poker probability and frequency is proven by precise mathematical calculations. It means that a four-of-a-kind, which is generally considered a strong card combination, has little probability and frequency because of its relatively high value. On the contrary, low poker hands such as the no pair/high card, two pair, and three-of-a-kind have higher probability and frequency due to their relatively low value.
