A spinner from a board game randomly indicates a real number between 0 and 10. The spinner is fair in the sense that it indicates a number in a given interval with the same probability as it indicates a number in any other interval of the same length. (a) Explain why the function fsxd H 0.1 0 if 0 < x < 10 if x , 0 or x . 10 is a probability density function for the spinners values. (b) What does your intuition tell you about the value of the mean? Check your guess by evaluating an integral.
