STD X – PROBABILITY – EINSTEIN
About Course
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.
Probability is the branch of mathematics that describes randomness. The
conflict between probability theory and students’ view of the world is due at
least in part to students’ limited contact with randomness. We must therefore
prepare the way for the study of chance by providing experience with random
behavior early in the mathematics curriculum
RANDOM EXPERIMENTS:
A Random Experiment is an experiment, trial, or observation that can be repeated numerous times under the same conditions. The outcome of an individual random experiment must be independent and identically distributed. It must in no way be affected by any previous outcome and cannot be predicted with certainty
SAMPLE SPACE:
A sample space is a collection or a set of possible outcomes of a random experiment. The sample space is represented using the symbol, “S”. The subset of possible outcomes of an experiment is called events. A sample space may contain a number of outcomes which depends on the experiment
EVENTS:
In probability theory, an event is an outcome or defined collection of outcomes of a random experiment. Since the collection of all possible outcomes to a random experiment is called the sample space, another definiton of event is any subset of a sample space.
