a. The number of people in a restaurant that has a capacity of 100.
You cannot have half a person, for example.
The possible number of people in the restaurant are 0, 1, 2,..., 100. So this variable is discrete.
b. The height of a randomly selected giraffe.
The giraffe can have half a meter, for example. That is, the height can be a decimal number. So this variable is continuous
c. The square footage of a house.
You can have half a square, for example. So this variable is continuous.
