Discover what a log-normal distribution is, its financial applications, and how to calculate it, including using Excel for ...

A t-distribution is a type of probability function that is used for estimating population parameters for small sample sizes or unknown variances.

You can use the RAND () function to establish probability and create a random variable with normal distribution.

The function can be set up for classical probability, but it's considerably easier to just construct the formula yourself, especially for a large range of outcomes.
