WebLeft Tail Probability. In contrast, when we want to know the probability of a value equal to or less than a value, this would be a left tail probability. The image below shows what a left-tail probability looks like on a normal distribution. While you can find the left-tail z-table for this, you can also just use 1 minus the right tail probability. WebA fat-tailed distribution is a distribution for which the probability density function, for large x, goes to zero as a power . Since such a power is always bounded below by the …
