​Really Small Numbers

​The Powerball® Lottery costs $2.00 to play.  For your two dollars, you get five numbers out of a group of 69 numbers, and from a separate group of 26 numbers, you get one number (the “Powerball”).  To win the jackpot, you must match all five numbers and the Powerball.  But, what is the probability of this actually occurring?

​Well, it's this: 1/292,201,338

​

• ​But,... how do we comprehend how small this number is?

• ​Suppose, after this class, you are so fed up with the day that you decide to take a road trip.

• ​And... for some strange reason, you will drive 292,201,338 centimeters.

• ​Where would you end up?

• ​We will all start here at East High.

​Perhaps a Map will help?
