❓ Frequently Asked Questions
What is probability?
Probability measures how likely an event is, ranging from 0 to 1. For a finite sample space, P(A) = number of favorable outcomes / total outcomes; for continuous cases, probabilities are defined via measures and densities.
How do you compute conditional probability?
Conditional probability is the probability of A given B: P(A|B) = P(A ∩ B) / P(B), provided P(B) > 0.
What does independence mean in probability?
Two events A and B are independent if P(A ∩ B) = P(A)P(B); knowing B occurred does not change the probability of A.
What is Bayes' theorem?
Bayes' theorem relates P(A|B) to P(B|A) and P(A): P(A|B) = P(B|A)P(A) / P(B). It updates beliefs after new evidence.
What is the Law of Total Probability?
If Bi form a partition of the sample space, then P(A) = Σ P(A|Bi)P(Bi). It expresses P(A) by conditioning on mutually exclusive cases.
