Formula: P(A) = Favorable / Total. P(A^c) = 1 - P(A). Percentage = P(A) * 100%.

In-Depth Guide & Mathematical Methodology

🎲 Classical Probability Axioms

Range: 0 ≤ P(A) ≤ 1 (0% impossible event, 100% certain event).

Complementary Rule: P(A^c) = 1 - P(A).

Odds: Ratio of favorable to unfavorable outcomes (P / (1-P)).
