Section 7.7

Confusion of the Inverse


A coincidence is a surprising concurrence of events, perceived as meaningfully related, with no apparent causal connection.

The Gambler's Fallacy

Section 7.1

Random Circumstance - One in which the outcome is unpredictable.

Probability - is a number between 0 and 1 that is assigned to a possible outcome of a random circumstance.

Section 7.3

Assigning Probabilities to Simple Events

Complementary Events

One event is the complement of another event if the two events do not contain any of the same simple events and together they cover the entire sample space. For an event A, the notation A^c represents the complement of A.

Mutually Exclusive Events

Two events are mutually exclusive they do not contain any of the same simple events (outcomes). The term disjoint is also used in the same regard.

Independent and Dependent Events

Conditional Probabilites

The event B, given that the event A occurs, is the long-run relative frequency with which event B occurs when circumstances are such that a also occurs. This probability is written as P(B|A)

Rule Four

Sampling with and Without Replacement

Larger samples do not require replacement, as the sample size would make the outcome insigificant.
