Mathematical Concepts

Probability
Discrete Random Variables
Probability Mass Function (PMF)

Formulas

p(X = k) = a / [k(k+1)]
p(1 ≤ X ≤ 3) = p(X=1) + p(X=2) + p(X=3)
Sum of probabilities for a PMF: p(X=1) + p(X=2) + p(X=3) + p(X=4) = 1

Theorems

Total probability must equal 1 for a discrete random variable
