Answer 1

A variable is discrete if only a limited number of values thr variable can take in a given interval. If there are infinite values possible in any interval, the variable is continuous.

Number of books in the classroom - discrete
Time it takes for students to finish their lunch - continuous
Age in years - continuous
Numeric date of birth - discrete
Shoe size - discrete (even if leg size is measured as a continuous variable, shoe sizes available have limited number of fixed values, making it discrete)
Number of students that bring their lunch to school - discrete
