Probability
- Basic Concepts
- Outcomes
- The possible results of the experiment
- Sample space
- Set of all the possible outcomes
- Event
- Some particular collection of the
possible outcomes
- Experiments
- All tests, random phenomenon
- Probability Formulas
- Empirical
- Theorical
- Events involvig"not" and
"or"
- Properties
- Certain event
Anmerkungen:
- The probability of certain event is 1.
The probability of an event is a number 0 through 1, inclusive.
- P(S)=1
- Probability value
Anmerkungen:
- The probability of an event is a number 0 through 1, inclusive.
- 0≤ P(E) ≤1
- Impossible event
Anmerkungen:
- The probability of an impossible event is 0.
- P (0) = 0
- Addition rule of probability
Anmerkungen:
- P (A U B)= P (A) + P (B) - P (A ∩ B)
- Mutually exclusive events
- P (A U B)= P(A) + P (B)
- Probability of the complement
- P (No E) = 1 - P (E) or P(E') = 1 - P(E)
- Set Operations
- Intersection
- Union
- Complement
- Difference
- Events involving
"and"
- Conditional probability formula
Anmerkungen:
- The probability of event B, computed on the assumption that event A has happened.
- Multiplication rule of probability
- For independt events
- P (A and B) = P(A) * P(B)
- For any two events
- P(A and B)= P(A)* P(B|A)
