• $$P(A) = \frac{Number\; of\; favorable\; outcome}{Total\; number \;of\; favorable \;outcomes}$$
• Probability Range: 0 ≤ P(A) ≤ 1
• Rule of Complementary Events: P(AC) + P(A) = 1
• Rule of Addition: P(A∪B) = P(A) + P(B) – P(A∩B)
• Disjoint Events: Events A and B are disjoint if: P(A∩B) = 0
• Conditional Probability: P(A | B) = P(A∩B) / P(B)
• Bayes Formula: P(A | B) = P(B | A) ⋅ P(A) / P(B)
• Independent Events: Events A and B are independent if: P(A∩B) = P(A) ⋅ P(B)
• Cumulative Distribution Function: FX(x) = P(Xx)
• Commutative: $$A\cup B = B\cup A$$ and $$A\cap B = B\cap A$$
• Associative: $$A\cup (B\cup C) = A\cup (B\cup C)$$ and $$A\cap (B\cap C) = A\cap (B\cap C)$$
• Neutral element: $$A\cup \theta = A$$ and $$A\cap E = A$$
• Absorbing element: $$A\cup E = E$$ and $$A\cap \theta = \theta$$
• Distributive: $$A\cup (B\cap C)=(A\cup B)\cap (A\cup C)$$ and $$A\cap (B\cup C)=(A\cap B)\cup (A\cap C)$$
• De Morgan’s law: $$\bar(A\cap B) = \bar A \cup \bar B$$ and $$\bar(A\cup B) = \bar A \cap \bar B$$
• Independent Events: $$P(A | B)=P(A)$$ and $$P(A\cap B)=P(A)×P(B)$$
• Conditional Probability: $$P(A | B)=\frac{P(A\cap B)}{P(B)}$$
• Laplace laws: $$P(A)=\frac{Number\;of\;ways\;it\;can\;happen}{Total\;Number\;of\;Outcomes}$$
• Complement of an Event: $$P(\bar A)=1 – P(A)$$
• Union of Events: $$P(A\cup B)=P(A)+P(B)−P(A\cap B)$$
• Permutation: $$P_{n}= n! = n\times (n-1)\times . .\times 2\times 1$$
• Permutations without repetition: $$^nA_{p} = \frac{n!}{(n-p)!}$$
