Match the distribution with its corresponding probability density/mass function.
Distribution type: (P) Binomial Distribution, (Q) Poisson Distribution, (R) Normal Distribution, (S) Exponential Distribution
Probability density/mass function:
(1) f(x) = (1/(σ√2π)) exp(-(1/2)((x-μ)/σ)2), σ > 0
(2) f(x) = (n choose x) px(1-p)n-x, x = 0,1,2,...,n
(3) f(x) = (μx/x!) exp(-μ), x = 0,1,2,...
(4) f(x) = λ exp(-λx), x > 0
