Precalculus: Chapter 9 Intro to Probability
Definitions:
Probability of an Event (Equally Likely Outcomes)
If E is an event in a finite, nonempty sample space S of equally likely outcomes, then the probability of the
event E is
Ex: Find the probability of rolling an odd number on a single roll of a fair die.
Probability of an Event (Not Equally Likely Outcomes)
Ex: Find the probability of rolling a total of less than 6 on a single roll of two fair dice.
Outcome
Probability
Determining Probabilities
Ex: What is the probability of drawing 2 aces from a standard deck of cards?
Then what would be the probability of not choosing two aces from a standard deck of cards?
Ex: a) Find the probability of drawing an ace or a king from a deck of cards.
b) Find the probability of drawing an ace and a king from a deck of cards.
