PROBABILITY

PROBABILITY

1. random experiment may result in two or more outcomes eg. tossing a coin

2. set of all possible outcomes of an experiment

3. an outcome of a random experiment or an event is something that happens

4. the different outcomes have the same as equal chances of occurence

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

6. probability of an event is equal to 0

   • probability of an event is equal to 1
   • P(E)+P(E)=1 or P(E)=1-P(E) here P(E)=P(not E)=complementary events
