First, watch the video below for a quick refresher on basic probability: Determine the individual probability (P) of each event that is to be combined. Calculate the ratio m/M where m is the number of outcomes that result in the event of interest and M is all possible outcomes. For exam...

There are two ways to calculate the possible combinations of four numbers if the options for each number are 0 through 9. The different ways depend on whether we are allowed to repeat a number in the sequence or if each number in the four-number sequence must be unique. Thes...
The attrition rate measures the number of employees who’ve left an organisation within a set period of time. Learn to calculate & decrease this number.
Simulations are relatively optimistic. It can also be difficult to calculate the VaR for large portfolios: you can't simply calculate the VaR for each asset, since many of those assets will be correlated. Finally, any VaR calculation is only as good as the data and assumptions that go into...
A permutation calculates the number of outcomes where order of events matters, but not all outcomes are equally probable or favorable. Learn how to calculate the probability of permutations using functions and factorials. Probability A probability is the likelihood of an event occurring. When ...

(with rational entries), and then use a linear algebra package that supports rational numbers to calculate the exact probability. it could turn out the the exact probability is a very complicated number – with very large numerator and denominator, but the computer can ...
