Which of the following can be represented by a discrete random

variable? Correct Answer The time of a flight between Chicago and

New York Correct Answer The average distance achieved in a series

of long jumps Correct Answer The number of defective light bulbs

in a sample of five Correct Answer The circumference of a randomly

generated circle

## Answer

[ANSWER]

The number of defective light bulbs in a sample of five

REASON:

A discrete variable is a variable which can only take a

countable number of values. In this example, the number of heads

can only take 4 values (0, 1, 2, 3) and so the variable is

discrete.
