Final answer:

The time it takes to drive from City A to City B and the distance a football travels in the air after being thrown are examples of continuous random variables, while the number of pigeons in a country is a discrete random variable.

Step-by-step explanation:

The type of random variable is determined by how its values are obtained. A continuous random variable is one whose values are obtained by measuring, while a discrete random variable is one whose values are obtained by counting. Let's analyze each case:

The time it takes to drive from City A to City B is a continuous random variable because it involves measuring time.

D: The distance a football travels in the air after being thrown is also a continuous random variable because it involves measuring distance.F: The exact time it takes to evaluate 67+29 is not a random variable because it is a fixed value. It does not involve any randomness or variation.E: The number of pigeons in a country is a discrete random variable because it involves counting the number of pigeons.A: The last book a person in City A read is not clearly defined, so we cannot determine if it is a random variable or not.B: The time it takes for a light bulb to burn out is not a random variable because it is a fixed value. It does not involve any randomness or variation.
