ECO 3401 Chapter Notes - Chapter 4.1: Empirical Probability, Mutual Exclusivity, Null Set
Document Summary
Part b: sample spaces: experiment an activity or occurrence with an observable result, ex. Tossing a coin, rolling dice, picking a card from a deck: random experiment has outcomes we cannot predict. Experiments involve chance or random results: trial repetition from a random experiment. The amount of times an experiment is performed: outcomes possible results of each trial, sample space set of all possible outcomes, outcomes written in brackets, ex. {1,2,3,4: sample point each element of the sample space, also called simple outcome. Part c: sample spaces example: two coins are tossed. Give the sample space where each outcome is equally likely: create a tree diagram, sample space: {ht,hh,th,tt, multiplication principle: number of outcomes equals #s(cid:894)(cid:1005)(cid:895) * #s(cid:894)(cid:1006)(cid:895) , ex. A coin has 2 possible outcomes when flipped. Two coins flipped would produce a sample space with 4 possible outcomes (2 x 2). Add another coin and the sample space increases to 8 sample points (2 x.
