Question 1<\/h3>\r\nIn the preview assignment, you used a random number generator to run a chance experiment that involved selecting a number between 1 and 10 a total of 100 times (with replacement).\r\n\r\n\"7A-InClass\r\n\r\nCredit: iStock\/amitus\r\n

Six of the ducks are designated as winners with a large dot on the bottom of each winning duck. To play the duck pond game, participants choose a duck and turn it over to discover if they chose a winning duck.\r\n\r\nEvery carnival attendee is allowed to play the game once for free. Participants can win a prize. Of the 20 ducks in the pond, two ducks are $10 winners, four ducks are $5 winners, and the rest of the ducks are not winners ($0).\r\n

    Question 3<\/h3>\r\nMake some predictions. If 100 people played the game:\r\n
      \r\n \t
    1. How many $10 prizes would the school give out?<\/li>\r\n \t
    2. How many $5 prizes would the school give out?<\/li>\r\n \t

    4. How much money in prizes would the school award, in total?<\/li>\r\n<\/ol>\r\n<\/div>\r\n
      \r\n

      Question 4<\/h3>\r\nIf 100 people played the game, what would be the prize awarded per game, on average?\r\n\r\n<\/div>\r\n
      \r\n

      Question 5<\/h3>\r\nIf 1,000 people played the game, what would be the prize awarded per game, on average?\r\n\r\n<\/div>\r\n

      Question 6<\/h3>\r\nLet's pretend that we are playing the game. Use the DCMP Random Number Generator. Let 1 and 2 represent the $10 prize ducks and let 3\u20136 represent the $5 prize ducks.\r\n\r\nDirect link: https:\/\/dcmathpathways.shinyapps.io\/RandomNumbers\/<\/a>\r\n\r\n\"\"\r\n

          \r\n \t
        1. In your class simulation, how much money was paid out by the school in prizes, in total and on average?<\/li>\r\n \t
        2. Is the average prize award per game close to the value calculated from theoretical probability?<\/li>\r\n<\/ol>\r\n<\/div>\r\nWhat we are seeing here is referred to as the Law of Large Numbers.
