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.
The Standard Normal Distribution. The standard normal distribution is a normal distribution with a mean of zero and standard deviation of 1. The standard normal distribution is centered at zero and the degree to which a given measurement deviates from the mean is given by the standard deviation.or the standard normal distribution, 68% of the observations lie within 1 standard deviation of the mean; 95% lie within two standard deviation of the mean; and 99.9% lie within 3 standard deviations of the mean. To this point, we have been using X to denote the variable of interest (e.g., X=BMI, X=height, X=weight).
