Math Lesson 10


Probability A number from 0 to 1 (or 0% to 100%) that describes how likely an event is to occur.
Experiment In probability, any activity based on a chance, such as tossing a coin.
Outcome A possible result of a probability experiment.
Equally like outcomes Outcomes that have seen the same probability.
Certain (probability) Sure to happen; having a probability of 1.
Impossible Probability Can Never Happen; having a probability of 0.
Experimental Probability The ratio of the number of times an event occurs to the total number of trials, or times that the activity is performed.
Trial A single repletion or observation of an experiment
Fundamental counting principal if one event has m possible outcomes and a second event has n possible outcomes after the first event has occurred, then there are m x n total possible outcomes for the two events.
Sample Space all possible outcomes of an experiment
Favorable outcome An outcome you are looking for when conducting an experiment.
Theoretical probability The ratio of the number of equally likely outcomes in an event to the total number of possible outcomes
Fair When all outcomes of an experiment are equally likely, the experiment is said to be fair.
Independent Event Events for which the outcome of one event does not affect the probability of the other
Dependent Event Events for which the outcome of the first event affects the outcome of the second event.
