Basic Probability Concepts
P(E) = Number of favorable outcomes / Total number of outcomesP(E) + P(E') = 1P(A ∩ B) = P(A) × P(B)P(A ∪ B) = P(A) + P(B) - P(A ∩ B)Cards and Dice Problems
Dice: P(sum = n) = Count of favorable combinations / 36Conditional Probability
P(A|B) = P(A ∩ B) / P(B)P(A ∩ B) = P(A|B) × P(B) = P(B|A) × P(A)Combinations in Probability
P(r successes in n trials) = nCr × p^r × (1-p)^(n-r)Expected value = Σ(outcome × probability)Get the complete formula sheet with derivations — continue in Super Tutor
