PROBABILITY

PROBABILITY

1. THEORITICAL PROBABILITY

   • 0<P(E)<1
   • P(E)=(Favourable outcome)/ (Total number of outcomes)

2. EXAMPLES

   • COIN
     • Total outcomes = 2 Favourable outcomes = 1 P(E)= 1/2
   • DICE
     • Total outcomes = 36 favourable outcomes = 6 P(E) = 1/6

3. EXPERIMENTAL PROBABILITY

   • EVENT
     • elementary event
     • compound event
     • quality like event
   • SPECIAL EVENT
     • sure(certain) event
     • impossible event
     • complement of an event

4. DEFINITION

   • Probability is a quantitative meaure of likelihood of a given events occurrence. It is measured by a number between 0 and 1.
