Lessons for S.MD.A.3
The binomial distributionCount successes in a fixed number of independent tries.Lesson
Mean and standard deviation of a binomialThe expected number of successes is the number of trials times the chance of success on one trial.Lesson
Expected valueEach value is weighted by how likely it is, so likelier values pull the average toward themselves.Lesson
The geometric distributionThe chance the first success lands on a given trial is a run of failures followed by one success.Lesson
Mean and standard deviation of a geometric random variableOn average the first success arrives after one over p tries, with a standard deviation of the square root of one minus p, over p.Lesson
Random variables and probability distributionsLaying out the values in one row and their probabilities in the next so the whole distribution is visible.Lesson
Random variablesA number attached to each outcome, and the distribution of those numbers.Lesson
