A. The probability of both success and failure remains constant → I. Binomial Distribution In a binomial distribution, the probability of success (p) and failure (q) remains constant for each trial.
B. The mean of distribution may be negative or positive → III. Normal Distribution A normal distribution is symmetric and its mean can take any real value, positive or negative.
C. The sum of all probabilities is equal to 1 → IV. Random Variable For a random variable, the total probability of all possible outcomes must be equal to 1.
D. The probability of occurrence of an outcome within a very small time period is very small → II. Poisson Distribution Poisson distribution is used for rare events occurring over a short interval of time or space.
