Probability Fair

 To wrap up our math unit on probability the grade 8’s from Mr. Lieberman’s class hosted a Probability Fair for the other intermediate classes. The students created their own game and calculated the theoretical probability of all of the possible outcomes for their game. At the same time, they had to make sure their game was profitable; in other words the host had greater than a 50% chance of winning. The probability games had to include at least two aspects where probability came into play. Some of the games featured spinners, dice, cards, grab bags, and the always flashy and fun Plinko-style ball drop. Cost and payouts had to be considered and large-print signs and high energy would help to attract more players to their games. Everyone had a blast; even the players that learned a valuable life lesson about the downfalls of gambling against the house and against the odds.
