Combinatorial Probability in Poker

The video tutorial explains combinatorial probability using poker as an example. It covers the basics of card suits and denominations, and then delves into calculating the probability of getting a pair in poker. The process involves determining the number of ways to get a pair and three singles, and calculating the numerator and denominator for the probability. The video concludes with the final probability calculation, explaining why a pair is not highly valued in poker.
