  • DEFINITION : Probability is the measure of how likely an event is.ExperimentOutcomeEventIt explains random phenomena.

  • HISTORYGerolamo Cardano September 24, 1501 September 21, 1576

    Known as the Father of ProbabilityWrote the book Liber de Ludo Aleae(The Book on Games of Chance) Used principles of probability in gambling

  • WHAT's MORE WITH PROBABILITY ?Probability-from the word "probabilitas" meaning "probity", a measure of the authority of a witness in a legal case in Europe.

  • TYPESTheoretical probability-is the probability of an event to happen. It is what you expect for an event to happen.

  • Theoretical probabilityWhat is the theoretical probability of getting YELLOW?number of favorable outcomes total number of outcomes= 14

  • Experimental probability TYPES-is the actual results of the activity or event. It is the comparison of the outcomes after certain trials was done.

  • Experimental probabilityWhat is the experimental probability of getting YELLOW?number of occurences number of trials= 2060=13

  • EXAMPLE

  • Equiprobable EventsThere are 36 possible combinations , each with exactly the same happenings. Out of 36:- Player 1: 16- Player 2: 20

  • Probability of Independent EventsThere will be 4 out of 6 chances of winning for the Player 1.

    Thus, having probability.

    = probability for Player 2.

    deal with uncertainties -- > realm of probabiltyThe word probability derives from the Latin probabilitas, which can also mean "probity", a measure of the authority of a witness in a legal case in Europe, and often correlated with the witness's nobility. In a sense, this differs much from the modern meaning of probability, which, in contrast, is a measure of the weight of empirical evidence, and is arrived at from inductive reasoning and statistical inference.[9]
