PROBABILITY

PROBABILITY

1. Probability of any event can never be less than or equal to 1

2. Random experiment may result in 2 or more outcomes

3. the differentoutcomes have the same as equal chance of outcomes is equally likely events

4. Set of all different outcomes of an experiment is sample space

5. Probability of an event is equal to 1 is known as certain event

6. Probability of an event is equal to 0 is impossible event

7. An outcomes of a random experiment or event is something to happen is known as event

8. Sum of the probability of all events is always one

9. No of trials in P[E]=which the event happened /total no of trials

10. When probability is based on an actual experiment suppose event E is happen,when experiment is performed is called emphirical probability

11. When repetition of an experiment can be avoided for exact probability is called measurement probability

12. Probability of an event denotes liklehhod of its happening is called classical probability
