5. Which is true of dependent events? You can find the AND probability of dependent events using the formula P(A or B) = P(A) · P(B). The outcome of one event has no effect on the outcome of a second event. You can use a two-way frequency table to calculate the conditional probability of events that are dependent. The probability of all dependent events can be calculated using the OR formula P(A or B) = P(A) + P(B) – P(A and B).
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
Dependent event
Two events are said to be dependent if the occurrence of one event depend on the happening of the other events.
