Other ways in which a life insurance policy can be leveraged to cover long-term care include purchasing a policy with an accelerated death benefit, or ADB. This is a feature that essentially allows you to get an advance on your death benefit to pay for care while you're alive.
In probability theory, the normal (or Gaussian) distribution is a very common continuous probability distribution. Normal distributions are important in statistics and are often used in the natural and social sciences to represent real-valued random variables whose distributions are not known.
A random variable X whose distribution has the shape of a normal curve is called a normal random variable. Normal Curve. This random variable X is said to be normally distributed with mean Î¼ and standard deviation Ï if its probability distribution is given by. `f(X)=1/(sigmasqrt(2pi))e^(-(x-mu)^2 /2\ sigma^2`.he new distribution of the normal random variable Z with mean `0` and variance `1` (or standard deviation `1`) is called a standard normal distribution. Standardizing the distribution like this makes it much easier to calculate probabilities.
