Penney Ante-game coin made in 1969, a mathematician named Walter Penney. The two players to predict the three coin tosses. This provision appears in the first use of coin throws to win. Th. Kunde. .



  • Probability is difficult for some people to fully understand but you explain things clearly. I am studying for a degree in Mathematics and probability is my favourite part of Maths. After watching your videos you helped me fully understand this game so thank you.I wish when I worked things out on paper they were that neat.

  • Yea good explaination. Derren is pesuasive I could imagion him leading them on to take a choice with low probability then use the higher proberbility outcomes for himself. Well done with the diagrams helped.

  • I still don’t get it, it’s not the game “who has the most good picks” right? Otherwise it would still 50-50?? Well maybe I’m a dumbass :p…

  • …makes no sense …….???????

  • That was marvellous - and now my brain has turned to jelly! Great video. x

  • hmm im not entirely sure that the second video was neccisary, i thought it was pretty clear how it worked after the first video, very clever tho, sometimes the obvious, hides from those who over complicate things 🙂

  • The first video is the extreme case. It isn’t obvious in the other cases until you do the maths. However that is where most expanations on the web stop. But if you look at the large table in part 2, a lot of player 2’s choices just give him a 50% or worse chance. You have to do all this maths before you find the strategy. The idea of flipping the middle coin isn’t significant, it’s just a way to remember the best choice. And for four or more coins the way to remember best choice is different

  • But i am a little skeptical…Oh uhh did the explanation video came out i cant find it anywhere

  • Yes, search for user waackomann

  • Wow.This was really cool Thanks Very much!
