Question

hich of the following can be represented by a discrete random variable? multiple choice the number of obtained spots when rolling a six-sided die the height of college students the average outside temperature taken every day for two weeks the finishing time of participants in a cross-country meet

Answer 1

The option that can be represented by a discrete random variable is 'the number of obtained spots when rolling a six-sided die' since its outcomes are countable.

Step-by-step explanation:

Which of the following can be represented by a discrete random variable? The answer is 'the number of obtained spots when rolling a six-sided die'. Discrete random variables are those where the values are countable, such as the result of a die roll, which can take on a finite set of possible outcomes: 1, 2, 3, 4, 5, or 6. Height, average temperature, and finishing times, on the other hand, are examples of continuous random variables because they can take on an infinite number of possible values and are obtained through measurement, not counting.
