Explain why the following is or is not a valid probability distribution for the discrete random variable x.
 
  x 1 3 5 7 9
  p(x) .1 .1 .2 .1 .2

Question 2

A bottle contains 16 ounces of water. The variable x represents the volume, in ounces, of water remaining in the bottle after the first drink is taken. What are the natural bounds for the values of x? Is x discrete or continuous? Explain.
 
  What will be an ideal response?

Answer to Question 1

This is not a valid probability distribution because the sum of the probabilities is less than 1.

Answer to Question 2

natural bounds for x: 0 ounces and 16 ounces; The variable x is continuous since the values of x correspond to the points in some interval.
