Theoretical Distribution

Concept:A uniparametric distribution is characterized by exactly one parameter.Explanation:• Binomial distribution has two parameters: $n$ (number of trials) and $p$ (probability of success).• Poisson distribution has one parameter: $\lambda$ (mean and variance).• Normal distribution has two parameters: $\mu$ (mean) and $\sigma^2$ (variance).• Hypergeometric distribution has three parameters: $N$ (population size), $K$ (number of successes in population), and $n$ (sample size).Thus, only Poisson is uniparametric.Answer:B.
