Chapter 7, Problem 32P

In a lottery the player has to select several numbers out of a list. Write a user-defined function that generates a list of n integers that are uniformly distributed between the numbers a and b. All the selected numbers on the list must be different. For function name and arguments, use x—lotto (a, b, n) where the input arguments are the numbers a and b, and n, respectively. The output argument x is a vector with the selected numbers.

(a) Use the function to generate a list of seven numbers from the numbers I through 59.

(b) Use the function to generate a list of eight numbers from the numbers 50 through 65.

(c) Use the function to generate a list of nine numbers from the numbers -25 through -2.
