Formula Sheet — Probability

Important formulas and equations from Probability for AP ICET Quantitative Aptitude.

Formulas — Probability

Basic Probability Concepts

P(E) = Number of favorable outcomes / Total number of outcomes
P(E) + P(E') = 1
P(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 / 36

Conditional 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)
