PROBABILITY  For classes 8th, 9th, 10th, 11th Basic concepts of probability useful for classes 9, 10 and 11. Explanation with playing cards, tossing one coin, two coins and three coins. Probability of an event        =   If E is an event then :-  P(E) + P(notE) = 1 Probability of an event is greater than, equal to 0 but is less than, equal to 1. This is also be called as the range of Probability \[0\leq P(E)\leq 1\] Impossible Event:-   An event which never occur is called impossible event.  P(Impossible Event) = 0 Sure Event : An even which happens for sure is called sure event. Sure event is also be called as the certain event. P(Sure Event or Certain Event) = 1 Equally likely events :-   If every event of the sample space has equal possibility to happen, then the events are called equally likely events.
