New Resource for Deal or No Deal Probability Game

Deal or No Deal card game
Mr. Faris, a reader from the Federated States of Micronesia (shout out to all of my readers around the world!) took my Deal or No Deal probability game and created a spreadsheet that calculates the bankers' offer for you.  In the original card game, the bank offer is based on a randomly drawn card, not on the prize amounts left on the board.  Thus you often get offers that make no sense, which can take away from the game experience.

As he explains: "It calculates the banker's offer for you.  I came up with the formula for the offer by studying data from game shows.  It is very accurate and useful.  One variable I think is used in the real formula which I did not use is whether the expected value has gone up or down since the previous round."  There's also a version of the score cards included as a second worksheet.

Huge thanks to Mr. Faris for sharing this resource!

Have Students Design Their Own Probability Game (Update!)

A couple of years ago I shared Three Fun Probability Games & Projects.  One of my favorites was a Design Your Own Carnival Game activity I had found online.  The link had been dead for quite a while, which many readers had alerted me to. 

Good news: I've finally found a copy of the activity in my records.  To those who wanted it, here it is via Google Docs.
