A Sporting Goods Store Announces a "Wheel of Savings" Sale

Essay

A sporting goods store announces a "Wheel of Savings" sale. Customers select the merchandise they want to purchase, then
at the cash register they spin a wheel to determine the size of the discount they will receive. The wheel is divided into 12
regions, like a clock. Six of those regions are red, and award a 10% discount. The three white regions award a 20% discount
and two blue regions a 40% discount. The remaining region is gold, and a customer whose lucky spin lands there gets a 100%
discount - the merchandise is free! Show your work.
-As you wait your turn in line there are three gold winners in a row. A lively discussion
ensues between the next two customers. One thinks that streak about kills her chances of
winning free merchandise, as the wheel won't come up gold again for a very long time.
The other says that the wheel is clearly on a hot streak, so they are lucky to be next in line.
Comment on their opinions.
