निम्नलिखित प्रायिकता वितरणों को उनके पूर्ण निर्धारण के लिए आवश्यक मापदंडों (parameters) की संख्या के बढ़ते क्रम में व्यवस्थित कीजिए: A. पॉइसन वितरण (Poisson distribution) B. सामान्य वितरण (Normal distribution) C. द्विपद वितरण (Binomial distribution) D. एफ-वितरण (F-distribution)

The mean and standard deviation of a Binomial distribution with parameters n, p, and q (where q = 1 - p) are respectively:

In a Binomial Distribution, the formula for calculating the standard deviation is:

Given below are two statements: Statement I: The F-distribution is defined as the ratio of two independent chi-square random variables, each divided by its respective degrees of freedom. Statement II: The Student's t-distribution is symmetric about the origin (mean = 0) with a bell shape similar to the standard normal distribution.
