3.1 Discrete Random Variables
Here you’ll learn the definition of discrete random variables and how to make judgments about whether certain
values or sets of values fall into this category.
What do you think the probability is that it will rain on Monday? You watched the weather forecast yesterday and
the meteorologist said that the probability is 100% certain that it will rain on Monday and about 75% chance of rain
on Tuesday. Could the probability of rain ever be described by 200%? What about 12%?

In previous Concepts, we looked at the mathematics involved in probability events. We looked at examples of
eventAoccurring if eventBhad occurred (conditional events), of eventBbeing affected by the outcome of event
