Contingency Table

A table summarizing the frequency of occurrences of different combinations of two variables. Rows represent one variable, columns represent the other, and cells contain the counts for each combination.

Category

A group of outcomes in a contingency table that share a common characteristic. Typically represented as a row or column in the table.

Frequency

The entries in a contingency table, representing the number of times a specific combination of categories occurred.

Marginal Total

A sum of frequencies for a specific category across all other categories. Represented as a row total or a column total.

Probability Table

A table that represents the probabilities of different events occurring. In this context, it shows the likelihood of events 'A', 'B', 'C', and 'D' happening in relation to events 'F', 'G', and the total probability.

P(A and F)

The joint probability of event 'A' happening with event 'F'. It is represented by the number '5' in the table.

Probability of Event A

The probability of event 'A' occurring, regardless of the outcome of event 'F' or 'G'. It is calculated by considering all possible combinations of event 'A' with 'F' and 'G'.
