Step 1 of 2

Random variables that can assume a countable number (finite or infinite) of values are called discrete. Random variables that can assume values corresponding to any of the points contained in one or more intervals (i.e., values that are infinite and uncountable) are called continuous.

          (a) The closing price of a particular stock on the New York Stock Exchange is a continuous random variable because the value corresponds to any of the points in an interval.
