The theoretical probability of an event....
The experimental probability of an event....
The complement of an event....
Two events that can not happen at the same time
The probability of an event occuring when an experiment was conducted
Based on events that have already occured
Probability based on reasoning, the mathematical expectation
A ratio of the number of favorable outcomes to the number of possible outcomes
The set of elements in either set or both
The set of all elements that belong to both the sets
The probability of something that will happen
Likelihood
Unlikelihood
A diagram representing mathematical or logical sets as circles within a rectangle. Common elements are shown through the intersection(s) of the circle(s)
All outcomes that are not the event
A set that contains nothing
A test or series of tests/experiments
Long Run Proportion
A set of all the possible outcomes of a trial
A possible result of an experiment/trial
Two or more possible outcomes that have the same probability
To find the experimental probability of an event, you need to conduct an experiment and record the number of times the event occurs as well as the number of times the activity is performed. Divide these numbers to find the answer
To find the theoretical probability of an event, divide the number of favorable outcomes to the number of total outcomes
Always adds up to 1
Number of ways it can happen divided by the total number of outcomes
Ratio of favorable outcomes to the total number of trials in an experiment, after conducting many trials
E.g. turning left and right simultaneously
One of more outcomes
E.g. The toss of a coin, spin of a spinner or roll of a die
