Unfortunately, on free course if I don't like it, I just swipe left and give negative feedback. On paid course, you give positive feedback before you see anything.
Puck needs an additional 4 clubs or hearts from the five common cards This is a hypergeometric distribution: N = 50 A = 12 n = 5 x = 4, 5 But, Puck can also get a “flush” if all 5 common cards are of the same suit! P(Clubs flush)+ 0.00925 =1-HYPGEOM.DIST(3,5,12,50,TRUE) Total Probability P(Hearts flush)+ 0.00925 =1-HYPGEOM.DIST(3,5,12,50,TRUE) P(Spades flush)+ 0.00061 =HYPGEOM.DIST(5,5,13,50,FALSE) P(Diamonds flush)+ 0.00061 =HYPGEOM.DIST(5,5,13,50,FALSE) Total Probability: 0.0197
I was scrolling the comment section to look for anyone with the answer to check if mine is correct and I only found yours, which was posted 1 day ago. I wonder if I had watched this video 2 days earlier, then I would have been quite upset for a few days to not know if my answer were correct. Thanks for your clear explanation also!!
love your vids, its just that my answers not always match yours , and ive no idea what i did wrong , you should also include every correct answer with its process even if its brief, thanks a lot for making these videos, you are of great help and a great explainer.
I watched your previous videos and learned a lot. May God bless you 💕 But please please please use proper formula along with the excel formulas. Because we're not gonna use excel in our exams....
Great teaching sir, this helped me build a firm foundation in Distribution stuff. But I plead you to make a video on Geometric Distribution, Uniform Distribution and Queueing Theory as well.
Thank you so much for making such a detailed explanation! BTW, what software did you use in the video? I notice that as your cursor was on the bar, it automatically showed the value, and I wonder how you did that with such an aesthetically pleasant design!
I would have benefited from a complete explanation of how to solve the problem since we can't use excel or programmable calculators but I did gain some value from the video. Thx.
Thank you so much for all your videos. They are intuitive and helpful. I have a quick question on the example of Texas Hold’em: why do we use N = 50 instead of N = 48? I think common cards will only be dealt when both players have been served their 2 cards, right? If we were to use 48, how does that change our approach to this question?
Hi Syao, given that you don't know your opponent's cards, you still treat it as if there are 50 unknowns. Quarantining 2 unknown cards for your opponent doesn't change what might happen to the 5 common cards. To prove this to yourself, imagine your opponent's cards are dealt after the common cards are shown. There's no real reason why this can't happen according to the game and SURELY this wont affect the probability of something that has already occurred.
This is unbelievable. I have to study for a statistics exams and I found your videos this week. Two of my three hobbies are basketball (especially watching NBA) and online poker. Should I also wait to see some video with chess? Much love, my gf is starting to get jealous!!
Dear instructor: I have got a question regarding the alternative Texas Hold´em "flushes". On the video, it is mentioned that the 5 cards on the table might be all the same suit, thus implying an extra flush. But, what about the other Hold´em players? They must have drawn their corresponding cards too, right? The feeling of targeting for alternatives flushes is just an uncertain illusion, because one does not know each of the pair of cards their opponents are seeing. Who would win in any case? The dealer? 🙃 Thanks in advance for your time. BTW, I am following the material you kindly provided. I appreciate the effort.
If there were for example 5 clubs on the board, every player has a flush. The tiebreaker would be if any one player holds a higher value club in their private hand, then their flush would be better than everyone else's. They would drop the lowest card from the communal five and use their own instead thus having a higher flush. If nobody has a better flush, the pot just gets split amongst the players.
Sir, I can't apply (FALSE) or (TRUE) in the end, I can only apply 4 numbers in the formula, otherwise I get an error, is that something wrong with my EXCEL, or they have something changed? Thank you!
Dear instructor, I have three questions regarding texas Holden example: 1. Poz's opponent will also be dealt two cards. So how can we consider N=50 while calculating dist? I should be 48. 2. There is a probability that Poz's opponent is also dealt a diamond or two. So that'll mean we can't take A=11. How do we account for this uncertainty? 3. In poker all the 5 cards are not dealt at once. They are dealt in succession so with each round of dealing, the probabilities will change. Am I understanding it correctly?
Ctrl+F for the comment by 'Syao'. He answered points 1 and 2 there. As for point 3, it doesn't matter which cards or what order of succession the cards are dealt with from the deck because we need 3 diamonds regardless of how they are dealt. After dealing to the players, you could set aside 5 face-down cards from the deck for the flop, turn and river. Whether these cards are from the top, bottom or middle of the deck makes no difference on the probability we need to get 3 of the desired suit.
