Answer
Explanation:
Step1: Recall variable - type definitions
A discrete random variable has a countable number of possible values. A continuous random variable can take on any value in an interval.
Step2: Analyze part a
The number of pigeons in a country is a countable quantity. So it is a discrete random variable.
Step3: Analyze part b
The "yes" or "no" response to a survey question is a categorical variable that can be coded as 0 (no) and 1 (yes). It is a discrete random variable.
Step4: Analyze part c
The number of free - throw attempts before the first shot is missed is a countable number (0, 1, 2, etc.). So it is a discrete random variable.
Step5: Analyze part d
The time it takes for a light bulb to burn out can take on any non - negative real value within an interval. It is a continuous random variable.
Step6: Analyze part e
The time required to upload a file to the Internet can take on any non - negative real value within an interval. It is a continuous random variable.
Step7: Analyze part f
The number of textbook authors now eating a meal is a countable quantity. So it is a discrete random variable.
