Bingo and Expected Value

I’ve been trying to find quick little probability related teasers to talk about in my non-Stats classes, and I think this is a great example of a quick problem for AP Stats and a quick thing to talk through in my other classes.

A few screenshots of the Bingo game that somehow ended up on my iPad and I play just because it’s there. They plan these things you see…every day I log in, I get 15 free tickets, and then you can get rewards for things and you get more free tickets. Tickets are good, because you buy bingo cards with them. The other thing you need is coins, to buy power-ups…

You get one free spin a day! And then you win that many coins! But what if I want more? You can always buy another spin…

Bingo Buy Spin

Worth it?

(Just one more…I’m sure I’ll win this time…)

    Hi,

    I came across your blog via David Wees, and as a fellow mathematics educator I thought you might be able to help in spreading the word about an educational TV show for preteens about math that we’re putting together. “The Number Hunter” is a cross between Bill Nye The Science Guy and The Crocodile Hunter — bringing math to children in an innovative, adventurous way. I’d really appreciate your help in getting the word out about the project.

    I studied math education at Jacksonville University and the University of Florida. It became clear to me during my studies why we’re failing at teaching kids math. We’re teaching it all wrong! Bill Nye taught kids that science is FUN. He showed them the EXPLOSIONS first and then the kids went to school to learn WHY things exploded. Kids learn about dinosaurs and amoeba and weird ocean life to make them go “wow”. But what about math? You probably remember the dreaded worksheets. Ugh.

    I’m sure you know math is much more exciting than people think. Fractal Geometry was used to create “Star Wars” backdrops, binary code was invented in Africa, The Great Pyramids and The Mona Lisa, wouldn’t exist without geometry.
    Our concept is to create an exciting, web-based TV show that’s both fun and educational.

    If you could consider posting about the project on your blog, I’d very much appreciate it. Also, if you’d be interested in link exchanging (either on The Number Hunter site, which is in development, or on StatisticsHowTo.com which is a well-established site with 300,000 page views a month) please shoot me an email. We’re also always looking for input and ideas from other math educators!

    Thanks in advance for your help,

    Stephanie
