Storyboard Text

  • We have 2 bags. Bag A has 3 marbles, one red, one blue, and one green. And in Bag B there's one red and one blue. To win you have to pulled two same color Marble.
  • So in Bag A, there's 2/3 chance to find a match and in Bag B, there's 1/2 chance to find a match. So if you multiply 2/3 and 1/2 you get 1/3 chance one winning the game. and if multiply it by 10 you get 10/30 to win.
  • After 30 games, our results is 9/30 for the winning side, and 21/30 on the losing side. So our theory was close to our results we have. 
  • Even if we got one point off, we still knew what was going to happen by using the theoretical probability. If we used experimental, then it will just give us a guess not what will happen after the game.
  • Well since there is 9 parts and 4 Gold, which will be 4/9, maybe if we multiply by 10 like the marble game to see the full answer. Which will give us 40/90, and maybe multiply 10/30 by 3 which will give us 30/90. we can compare which one is bigger and it's 40/90 which is the spinner game.
  • Ohh, well then let's play!
  • So I made another game, and the colors are red, blue, and Gold. To win you have to spin on a Gold section. But I don't know which one has a higher chance of winning, the marble game or this one??
