WebJul 14, 2024 · A normal distribution is described using two parameters, the mean of the distribution μ and the standard deviation of the distribution σ. The notation that we sometimes use to say that a variable X is normally distributed is as follows: X∼Normal (μ,σ) Of course, that’s just notation. WebSep 18, 2024 · A binomial distribution graph where the probability of success does not equal the probability of failure looks like this. Now, when the probability of success = probability of failure, in such a situation, the graph of binomial distribution looks like The mean and variance of a binomial distribution are given by: Mean -> µ = n*p
