You meant we multiply it by 2, since order is Not important; if it was we wouldn't

Could you elaborate what the number from the formula represent? (The probability of getting dealt 2 suited cards one) I mean id do the 12/51 for that, but with this one,
the 52 choose 2 is all the ways we get 2 cards
but how you get 4*(13 choose 2) ?

4 because of 4 suits
13 choose 2. The number of combinations within 13 cards (all of one suit).
Now we have to divide by the number of all probabilities of having 2 cards (52 choose 2).

I agree that for just one suited cards it seems like much easier to write 12/51, but it might be easier to get youself used to the combinatorics. Especially, when you start counting combinations later to put people on a range (e.g. is it more likely that he has a flush draw or that he has a TP+ on the turn...).

Except for the math bits, i really enjoyed this video!

why is "A given B" the same as "A without B"?

I just started reading this book a couple weeks ago so excited that your doing this series!!! Thanks for doing it

why is "A given B" the same as "A without B"?

A more clear definition of A|B is the probability of A occurring given that B occurred


edit: mixed them up

I personally was thrilled to watch this series and i have to admit after watching it i really liked it alot, cant wait to see the next episode about the variance

@Bellatrix: You talked at the end of the video about homework, i noticed you talked also about it in your preview about it. What is your idea with that?

yeah I understand that, I just don't understand why "A without B" is the same thing.

This is not what pot odds means! Your pot odds here are 5.00 to 1 (20/100) and your chances of hitting are 4.75:1 (8/38). Pot odds is the price you're getting laid, not the chance of winning the pot.

Yeah, in the future, "A | B" means "A given B", any other explanation is confusing, I agree.

You can download the homework posted with this video, work through it and send it to my e-mail at DC (bellatrix@deucescracked.com). If you send something in, you get the solutions for you to compare, no grading. Please send in LaTeX files or scanned pages, no text formulas.

The homework will help you practice the stuff or at least internalize the concepts better than just listening to a video. It is 100% voluntary

Not really what i was expecting tbh. I literally just got Mathematics of Poker today in the post and read the first chapter followed by this video. I think without having read the first chapter in the book i would be lost and have come away with very little from this video. I dont expect you to follow the book exactly , however i thought you could of done a bit better at explaining some of it. I got the feeling 'probability' to you is pretty simple and you just briefly touched on it and breezed through it all rather quickly. I liked your explanation of dependent and independent events using the idea of a bowl of marbles. It was this different approach and actually hearing you discuss it that helped add to my understanding of what the book told me.

I looked at your homework , question 1 looks good.
Question 2 a) looks thought provoking - i like it
2 b) ive never played roulette , wouldnt know where to start.
Question 3 ' A team is favored to win a game (moneyline) at -250 (-180, -110, +300)' i have no idea what that means. I dont know what 'no juice' means either.

Not every poker player is from Las Vegas and a gambler in all forms.

Hope this post helps

I don't quite understand, you wouldn't have understood the video without reading the first chapter, but would like me to stay close to the book more? Like when I talked about G-bucks and Sklansky-bucks I veered off the book quite a lot. Do you feel I should just stick to the book?

For the homework terminology, google is your friend (e.g. rules of roulette, payout structures etc.). Note that these terms get thrown away all the time at the poker table (in live games), so you should probably familiarize yourself with gambling terms, but as always, nothing is absolutely necessary to win at poker, just every little bit helps.

Yes, calculating probabilities is just a first step and should come as second nature to you. If you feel lost in the first chapter, I would probably recommend "Mathematics of NL Hold'em" by Wilt on Tilt. He goes through that stuff much more slowly and in depth, because if I explain every step, the series would be just too long. I understand the best with examples, which is why I tried to sprinkle examples all throughout the video. We will come back to probability over and over again, so just keep at it and practice makes perfect.
