When you board a Ferris wheel moving counterclockwise at a constant rate, your feet are 5 feet off the ground. At the highest point of the ride, your feet are 55 feet above the ground. It takes 150 seconds for the ride to complete one full revolution. Write a set of parametric equations to model this situation, where t is time elapsed in seconds and h is height above the ground in feet

The probability would be 1/10000.  The expected value is a loss of $9.20.

There is exactly one number to match the winning 4 digit number in 10000 possible choices.

To find the expected value, we multiply each probability by its winnings or loss:
(1/10000)*(7990) = $0.799
(9999/10000)*(-10) = $-9.999

Adding these two, we get an expected loss of $9.20.
