What is a Probability Mass Function (PMF) in Statistics?

WebSep 18, 2024 · This is the set of all pairs of values within the support of the binomial that multiply to the value z. (Note that it will be an empty set for some values of z .) We then have: p Z ( z) ≡ P ( Z = z) = P ( X Y = z) = ∑ ( x, y) ∈ S ( z) Bin ( x ∣ n, p) ⋅ Bin ( y ∣ n, p) = ∑ ( x, y) ∈ S ( z) ( n x) ( n y) ⋅ p x + y ( 1 − p) 2 n − x − y.
