1. Gerardo Acosta Olvera A01400455

2. it has 4 basic concepts :

   • outcome: each one of the answers
   • sample space: all the answers
   • event:reduction of all the possibly outcomes
   • Experiments: an observation of all the things

3. formulas: theorical and empirical

   • Theo: # of favorable outcomes/ total outcomes
   • Empi: # of the things that have happened

4. probability

5. NOT and OR

   • properties of probability
     • certain event: P(E):1
     • impossible event: P(E):0
     • probability value: 0<P(E)<1
   • Aditional rule of probability: P(A or B) = P (A) + P(B)
   • mutually exclusive event
     • P(A)+P(B)-(P(A[intersection]B)

6. AND

   • multiplication rule of probability
     • for any two events :
       • P(A[intersection]B): p(A)*P(A/B)
     • for independetnd events
       • P(A[intersection]B): P(A)*P(B)
     • conditional probability formula:
       • P(A[intersection]B)/P(A)

7. Set Operations

   • Intersection:
   • complement
   • Difference
   • UNION

8. Statics basics concept

   • qualitive
     • something that you cant use to do an mathematic operation
   • quantitative
     • discrete
       • just can take a countable set like : 1 or 2 or 3
     • continuous
       • just cant take intervals in the countable set like 1.2 or 1.4 or 3.5
