Document Summary
If p(a) and p(b) equal p(a and b), it is independent. Discrete random variable: a specific list of values. For example: the number of people requesting a vegetarian meal on a flight. Continuous random variable: multiple decimal places or values. For example, the volume of ice cream in a scoop. Continuous variables can be added or subtracted to find a new distribution. The z table can be used to find the probabilities. When finding a new distribution, the sd"s are added to each other. Two types of outcomes (success and failure) Not associated with positive or negative results. To use the table: find n, p, and k, n = trials, p = probability of success, k = whatever the question asks for. To find if an event doesn"t happen. Disjoint: two events cannot happen at the same time. If one event occurred, the other"s probability is 0. Clinton and trump can"t be president at the same time.
