Unlock: Discrete and Continuous Distribution Pairs

A reference page mapping the canonical discrete-and-continuous companion pairs. Discrete uniform and continuous uniform; Bernoulli/Binomial counting process and the Poisson process; geometric and exponential waiting times (both memoryless); negative binomial and gamma (time to r-th event); hypergeometric (sampling without replacement, no clean continuous analog). Each pair is shown side by side with definition, PMF or PDF, support, mean, variance, MGF, memorylessness check, and conceptual bridge.
