An indifference curve is a graph showing combinations of goods for which a consumer is indifferent, that is, it has no preference for one combination versus another, as they render the same level of satisfaction (or the same amount of utility) for the consumer.
The theory of indifference curves was developed by Francis Ysidro Edgeworth, Vilfredo Pareto and others in the first part of the 20th century.
The idea of an indifference curve is a straightforward one: If a consumer was equally satisfied with 1 apple and 4 bananas, 2 apples and 2 bananas, or 5 apples and 1 banana, these combinations would all lie on the same indifference curve.
The principle of indifference states that if the n possibilities are indistinguishable except for their names, then each possibility is assigned a probability equal to 1/n.
The principle of indifference is meaningless under the frequency interpretation of probability, in which probabilities are relative frequencies rather than degrees of belief in uncertain propositions, conditional upon a state of information.
The theory of chance consists in reducing all the events of the same kind to a certain number of cases equally possible, that is to say, to such as we may be equally undecided about in regard to their existence, and in determining the number of cases favorable to the event whose probability is sought.
