probability/maine-standards?dictionary=probability&did=448" onclick="getAsistant(this,event,448,'probability');return false;" style="color:#009000;">Probability is a branch of mathematics that deals with the likelihood of a given event or outcome occurring. In everyday life, we use probability/maine-standards?dictionary=probability&did=448" onclick="getAsistant(this,event,448,'probability');return false;" style="color:#009000;">probability to make decisions, predict outcomes, and understand uncertainty. Understanding probability/maine-standards?dictionary=probability&did=448" onclick="getAsistant(this,event,448,'probability');return false;" style="color:#009000;">probability can help in making better decisions and analyzing various situations.
Key Concepts
probability/maine-standards?dictionary=probability&did=448" onclick="getAsistant(this,event,448,'probability');return false;" style="color:#009000;">Probability Scale:probability/maine-standards?dictionary=probability&did=448" onclick="getAsistant(this,event,448,'probability');return false;" style="color:#009000;">Probability is measured on a scale from 0 to 1, where 0 indicates impossibility and 1 indicates certainty.
Sample Space: The set of all possible outcomes of a random experiment is called the sample space.
Events: An event is a subset of the sample space, representing a specific outcome or a set of outcomes.
probability/maine-standards?dictionary=probability&did=448" onclick="getAsistant(this,event,448,'probability');return false;" style="color:#009000;">Probability of an Event: The probability/maine-standards?dictionary=probability&did=448" onclick="getAsistant(this,event,448,'probability');return false;" style="color:#009000;">probability of an event A, denoted as P(A), is the likelihood of event A occurring and is a number between 0 and 1.
probability/maine-standards?dictionary=addition&did=99" onclick="getAsistant(this,event,99,'addition');return false;" style="color:#009000;">Addition Rule: For any two events A and B, the probability/maine-standards?dictionary=probability&did=448" onclick="getAsistant(this,event,448,'probability');return false;" style="color:#009000;">probability of the union of A and B is given by P(A ∪ B) = P(A) + P(B) - P(A ∩ B).
probability/maine-standards?dictionary=multiplication&did=103" onclick="getAsistant(this,event,103,'multiplication');return false;" style="color:#009000;">Multiplication Rule: For independent events A and B, the probability/maine-standards?dictionary=probability&did=448" onclick="getAsistant(this,event,448,'probability');return false;" style="color:#009000;">probability of the intersection of A and B is given by P(A ∩ B) = P(A) * P(B).
