Answer :
Final answer:
The random variable in each scenario represents a different count of events - women Ted approaches, dates, marries, or becomes friends with. Random variables are used in probability and statistics to predict outcomes of random events.
Explanation:
In each scenario with Ted, the random variable (X) represents a different count of events. For scenario 1, the random variable X is the number of women Ted approaches. For scenario 2, X is the number of women Ted dates. In scenario 3, the variable X stands for the number of women Ted gets married to. And in scenario 4, it is the number of women Ted becomes friends with. In each case, we only know the specific value that the random variable X takes after performing the experiment - meaning, after observing Ted's behaviour and interactions.
As a concept, a random variable is a measurable function from a sample space to a mathematical space of possible values. They're often used in probability and statistics to predict the outcomes of random events.
