Probability

Probability

1. Types

   • Measurement Pobability
     • When repitition of an experiment can be avoided for exact probability.
   • Empirical Probability
     • When Probability is based on actual experiment suppose event E is happen, when experiment is performed
   • Classic Probability
     • Probability of an event denotes likelihood of its happening

2. Probability of Events

   • Sum
     • Sum of Probability of all events is always one
   • Complementary Event
     • P(E)+P(Ē)= 1 P(Ē)= Complementary events
   • Sure Events
     • Probability of an event is equal to 1
   • Impossible Event
     • Probability of an event is equal to 0

3. Random Experiment

   • Random Experiment may result in 2 or more outomes

4. Sample Space

   • Set of all possible outcomes of an experiment

5. Event

   • An outcomes of a random experiment

6. Equally likely Events

   • The different outcomes have the same as equal chance of occurrence

7. Probability of any event can never be less than 0 and not more than 1
