A discrete variable is a variable that can only take on specific, distinct values. The number of coins in a person's pocket and the number of heads that could appear on two flips of a fair coin are both examples of discrete variables because they can only take on certain values (i.e. you can't have 3.5 coins or 1.3 heads). Your exact age, however, is an example of a continuous variable because it can take on any value within a certain range (for example, you could be 26.234 years old).
