MAST 6201 Lecture Notes – Introduction/Kickoff 1. Why statistics? 2. Basic Probability Definitions: Outcome – a result, e.g., flipping a coin has two possible outcomes, Heads or Tails. Sample Space - The set of all possible outcomes. Event – a subset of the sample space (or grouping of outcomes). Trail – one run of the experiment. So if the experiment is the outcome of flipping a coin, a Trial is one flip of the coin. Two flips are two Trials. Probability – the relative likelihood that an event will occur, written as P(E) where E is an event. Compliment – If E is an event, the compliment of E (denoted E’) is everything in the sample space except E. For instance, if the sample space is a deck of cards and the event is that the card is a spade. The compliment of this event is all cards except the spades, e.g., clubs, hearts and diamonds. Also note that P ( E ) = 1 P ( E ' ) . Intersection – if A and B are two events, then the intersection (A ∩ B) is defined as both events occurring. So if A is a Heart, and B is a King, (A ∩ B) means the King of Hearts. Union – if A and B are two event, then it union ( A B ) is defined a one event or the other occurring. So if A is a Heart, and B is a King, ( A B ) means the card is either a King or a Hearts.

    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.
