PROBABILITY - Coggle Diagram

- - - - 0 ≤ P(A) ≥ 1
- - - - Thus, when we throw a coin we know that all possible outcomes are Head and Tail.
        But, if we throw a coin at random, we cannot predict in advance whether its upper face will show a head or a tail.
        
        So, tossing a coin is a random experiment.
        Similarly, throwing a dice is a random experiment.
  - - - EXAMPLE ⚠
        
        When an unbiased coin is tossed the chances of getting a head or a tail are the same.*
  - - - For example; if two dice are thrown, the number of favorable events of getting a sum 5 is four.
- - - - P (A or B) = P (A) + P (B)
  - - - P (A or B) = P (A) + (B) - P ( A and B)
