The Lucky WheelAt the Pennyfield fair, Mr. Odd kept a stall with a big wheel. His sign said Lucky Wheel, one coin a spin. The wheel had ten equal slots: nine plain and one gold. You put in one coin and spin. If the pointer stops on gold, six coins come back. On a plain slot, nothing does. Grandpa told Maya to count the slots. That count is called the odds, and one gold slot out of ten is one chance in ten. A boy named Kit spun three times. The first spin stopped on gold, so one coin brought six back. The next two spins were plain. Grandpa said that on average, ten spins cost ten coins and give back six, so the stall keeps the other four. Whoever runs a game like this is called the house. A short run can look different, but over many spins the coins drift toward the house's side, because odds decide the long run, not luck.
