Probability

Probability

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

2. Equally likely Events

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

3. Event

   • An outcomes of a random expeiment

4. Sample Space

   • Set of all possible outomes of an expeiment

5. Random Experiment

   • Random Experiment may result in 2 or more outcomes

6. Types

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

7. Probability of Events

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