PROBABLITY

PROBABLITY

1. TYPES

   • CLASSICAL PROBABILITY
     • Probability of an event denotes likelyhood of it's happening . P(E) = No.of event favourable / Total no.of all possible event
   • MEASUREMENT PROBABILITY
     • When repetition of an experiment can be avoided for exact probability. Probability = No.of favourable outcomes/No. of all possible outcomes
   • EMPIRICAL PROBABILITY
     • When probability is based on an actual experiment , suppose event E is happened ,when experiment is perfomed, then P(E) = No.of times event occurred/no.of times the experiment was performed

2. RANDOM EXPERIMENT

   • random experiment may result in two or more outcomes

3. SAMPLE SPACE

   • set of all possible outcomes of an experiment

4. EQUALLY LIKELY OUTCOMES

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