{/eq}Mean:One of the most important distributions in the theory of random variables is the binomial distribution. This discrete random variable is determined by two parameters that allow calculating its mean in a very simple way: {eq}X\~B\left( {n,p} \right) \to \mu =...
±σ = x - μ From this it is easy to see that the inflection points occur wherex = μ±σ. In other words the inflection points are located one standard deviation above the mean and one standard deviation below the mean.
Understand what a binomial random variable is. Learn how to find the mean or the expected value and the standard deviation of a binomial distribution using examples. Related to this Question Consider a binomial experiment with n=10 and pi=0.35. Let x denotes the...
To solve the problem, we need to find P(|X−4|≤2) given that X follows a binomial distribution with a mean of 4 and a variance of 2. 1. Understand the Mean and Variance of a Binomial Distribution: - The mean μ of a binomial distribution is given by μ=np. - The variance σ...
