Some Definitions for Probability (Part 2)

Independent Event- the outcome of one event has no effect on the outcome of another event
eg. flipping coin
     rolling a die
Sample Space- all possible outcomes of an experiment
eg. heads of tails (coin)
     1,2,3,4,5,6 (die)
Organize sample space using a chart of a tree diagram

Random- an event in which every outcome has an equal chance of occurring
eg. flipping a coin, rolling a standard die, or draw a card from a standard deck of cards

Theoretical Probability-the expected probability of an event occurring.
Experimental Probability-the probability of an event occurring based on experiment results
