Understanding Basic Probability Concepts
Probability quantifies the likelihood of an event occurring and ranges from 0 (impossible) to 1 (certain).
Basic Probability
For any two events \( A \) and \( B \), the probability of \( A \cup B \) (either \( A \) or \( B \) occurring) is given by:
\[ P(A \cup B) = P(A) + P(B) - P(A \cap B) \]If \( A \) and \( B \) are mutually exclusive (cannot occur simultaneously), then:
\[ P(A \cup B) = P(A) + P(B) \]Conditional Probability
The probability of event \( A \) occurring given that event \( B \) has occurred is called the conditional probability of \( A \) given \( B \), denoted by \( P(A|B) \), and is calculated as:
\[ P(A|B) = \frac{P(A \cap B)}{P(B)} \]Bayes' Theorem
Bayes' theorem relates the conditional and marginal probabilities of events \( A \) and \( B \):
\[ P(A|B) = \frac{P(B|A) \times P(A)}{P(B)} \]How to Use the Probability Calculator
