  10. 8bitmagic is right about the 13 and the hidden owl head on the top right that the artist snuck in.

  11. 8bitmagic says:
  12. but I thought the answer was 18
    1 Washington
    1 Eagle
    13 arrows (look closely)
    2 “heads” of treasury or whatever who signed the fron
    1 spider/owl head above and to the left of the 1

    I may be wrong about the signatures but even so you missed 2 heads

  13. TheRedLettuce says:
  14. count all the arrow heads, the eagle, Washington, the owl in the top left, and the spider’s head on the top right (for the spider and owl you need a microscope to see them.)

  15. SugarFreeNubCakes says:
  16. There are 13 arrow heads. Not 12.

  17. RisefromyourGRAVE says:
  18. duh… They were probably phd’s in fake sciences

  19. @BecuzIt Sorry for some reason I completely overlooked the word ‘to’. I’ll read twice before commenting next time. :)

  20. @Kuploosh No, my comment said “…odds of 1 to 2, which is the same as a probability of 1/3.”

    The odds in favor of an event is expressed as a RATIO of the probability of the event to the probability of its complement; in other words, favorable outcomes over unfavorable outcomes, NOT total outcomes. The odds of rolling a 1 on a die would be 1:5 for example

    I can see why you might have thought I was having confusion about the actual problem but you should have read carefully

  21. @BecuzIt Actually, if the other “goat” is revealed, and you are given the chance to switch, you will win 2 out of 3 times. If you always stick with your first choice, you will win 1 out of 3 times. Think of it this way. If you always switch, you can only lose if you initially picked the “car”. Since you have a 1/3 chance of picking the car first choice, you have a 2/3 chance of winning if you switch. Make sense?

  22. thepokemaster519 says:
  23. there are 15 heads the arrowheads, eagles head,whashingtons head, and the owl in the top right hand corner behind the 1

  24. I’ve got a better scam. If the contestant picks a goat end the game and don’t give him the chance to switch. If he stays when he has the chance to switch, he still wins 1 in 3. But if he switches he now loses all the time instead of winning 2 out of 3.

  26. I don’t think it’s really a paradox, but this is still a great video. :)

  27. MrRyan1789 says:
  28. one more head…the owl on the top left

  29. spinamajig says:
  30. Saw this on “numb3rs”! Freaking simple!

  31. in mathematical terms, odds would be 1 to 2, which is the same as a probability of 1/3. “odds” are expressed as favorable over unfavorable

    since it’s colloquial here , hardly a matter of consequence to most people, but still…

  33. @coprophob907 and the alien :)

  34. WhiteHenny says:
  35. @cblouin06 and this isn’t a paradox, why does he keep referring to it as a paradox?

  36. cblouin06 says:
  37. there are 13 arrow heads not 12……

  38. balloonchicken says:
  39. I’ve spent so much time explaining this to friends… It’s kind of a fun hobby! The main thing is there’s a 2/3 chance you don’t have the car. The host then opens a box which he knows doesn’t contain the car (he has added additional information). Since there was only a 1 in 3 chance your original choice was right, there will be a 2 in 3 chance of winning if you switch to the other box. Mike still doesn’t belive me.

  40. coprophob907 says:
