Probability

Probability. Definitions. Probability is the mathematics of chance. It tells us the relative frequency with which we can expect an event to occur. The greater the probability the more likely the event will occur. It can be written as a fraction, decimal, percent, or ratio. 1. Certain. .5.

Probability

Probability. Part 1. A Few Terms. Probability represents a (standardized) measure of chance, and quantifies uncertainty. Let S = sample space which is the set of all possible outcomes. An event is a set of possible outcomes that is of interest.

Probability

Probability. Definition. Probability: the proportion of times an event would occur if the chances for occurrence were infinite ( p . 123) A proportion is a number from 0 to 1. In probability, 1 means that the event will certainly occur, 0 means that the event will certainly not occur.

Conditional Probability

Conditional Probability. The idea. In general, the probability of an event is affected to some degree by the occurrence of other events. Example #1. A family with 2 children has moved onto your street. Let p(E) be the probability that the family has 2 boys. Find p(E). Example #2.
