PROBABILITY

PROBABILITY

1. Basic concepts

   • Sample space
   • Outcomes
   • Event
   • Experiments

2. Formulas

   • P (E)
     • #of times the event occurs
   • (n(E))/(n(S))
     • Favorable over total outcomes

3. Events involving not and or

   • Properties
     • certain event
     • Impossible event
     • Probability value
   • Addition rule of probability
     • P(AUB)=P(A)+P(B)-(P^B)

4. Events involving and

   • Conditional probability formula
     • ((P(A^B)/P(A)))
   • Multiplication rule
     • For any two events
     • For independent evets

5. Set operations

   • Intersection
   • Complement
   • Difference
   • Union
