This long article covers topics ranging from applied mathematics, statistics, probability, and algorithms, to computer sciences. Original, fun problems are discussed. Even thought you won't find them in textbooks or traditional data science courses, these problems do not require more than high school mathematics to explore solutions.

Listed on my personal website www.markmcilroy.com is my book titled 'A guide to writing Excel formulas and VBA macros'. The book is available for free download in PDF format. It is also available in print from Amazon.com.

Excel is widely used for all forms of data analysis once the bulk of the data has been processed and summarised using a tool such as SAS, SQL, etc.

The purpose of this article is to generate new theorems of probability and to find out some applications of these theorems. In this case, suppose that we have a covered basket that contains many dices. In many blind tests, we will reach in and pull out a dice and set it on the table on one row from left to right. It is clear, each dice has six events (choices) including 1, 2, 3, 4, 5, and 6. 

What is the application of these theorems (1 and 2)?

Let me…

I had no experience with SAS, and all I had to refer to was the existing code in the system and this book.

As the title suggests it's quite a small book in IT terms, the fifth edition is 325 pages.

One benefit of this is…

As you would know, SQL is essential for many tasks involving working with large quantities of data.
