32 CardsLesson#1
In this deck, we'll explore the basics of probability. You'll learn how to measure the chance of something happening, from impossible events to certain ones. We'll cover how to calculate the probability of a single event, and then look at powerful tools like Venn diagrams and tree diagrams to handle combined events.
Lesson#2
Probability is measured on a scale from 0 to 1. An event with a probability of 0 is impossible – it will never happen. An event with a probability of 1 is certain – it will definitely happen. Everything else falls somewhere in between.
Quiz#3
What is the probability of an event that is impossible?
0
Quiz#4
What is the probability of an event that is certain to happen?
1
Quiz#5
If an event is equally likely to happen as not to happen, what is its probability?
0.5
Lesson#6
A key rule in probability is that the probabilities of all possible outcomes of an event must add up to 1. For example, if you flip a coin, the probability of heads plus the probability of tails must equal 1.
