Determine whether the value is a discrete random variable co
     Determine whether the value is a discrete random variable, continuous random variable or not a random variable.  The number of textbook authors now sitting at a computer.  The number of people in a restaurant that has a capacity of 250.  The eye color of people on commercial aircraft flights.  The number of statistics students now reading a book.  The number of light bulbs that burn out in the next week in a room with 10 bulbs.  The distance a baseball travels in the air after being hit.  Is the number of light bulbs that bum out in the next week in a room with 10 bulbs a discrete random variable, a continuous random variable or not a random variable?  Is the distance a baseball travels in the air after hit a discrete random variable, a continuous random variable, or not a random variable?   
  
  Solution
Answer to the question)
All the values that cannot be expressed in decimals but cna be expressed in whole numbers is called discrete random variables
Following variables are discrete
.
The values that can be expressed as whole number and decimal as well are called Continuous Random variable
Distance a baseball travels can be a whole number and can be a expressed in decimals as well
thus distance is a continuous variable
.
The eye color can not be expressed in numbers . It is divided into various color types or groups or categories
Thus it is a non random variable
