Stats Test 2 Notes Classical Probability - # of outcomes in the event/ # of outcomes in sample space Empirical Probability – frequency of class/ total frequencies in distribution Addition Rule (OR problems)– P (A and B) = P (A) + P (B) – P (A and B) Mutually Exclusive Events – Events are mutually exclusive if they cannot occur at the same time (they have no outcomes in common) Mutually Inclusive Events - Events are mutually inclusive if they can occur at the same time (they have outcomes in common) Multiplication Rule (AND problems) – P (A and B) = P (A) * P (B|A) Independent Outcomes – Events A and B are independent if the fact that a occurs or does not occur has no effect on the probability of B occurring P (A and B) = P(A) * P(B) Dependent Outcomes – When the occurrence of the first outcome affects the occurrence of the next outcome HINTs: all, every, each, both Complement Steps: 1) Define the event 2) Define the complement of the event 3) Find the probability of the complement 4) Find the probability of the event

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
