Solved the first problem now and solved two more simple problems.

I solved two simple expectation problems and have four problems left to go in this week's home work. I also went back and solved the first problem using a floor operator which I learned about on wikipedia. I was taught the floor operator at one point in my mathematical education but had forgotten it and had digested it into an int function in computer programming. Anyway I now have my elegant solution to the first problem. I solved a mathematical guessing game.
