Consider the following scenario. There’s a marathon race arranged in your country and you are the organizer of…

As you may know, probability questions are frequently tested in the technical interviews for Data Scientist, Data Analyst even ML Engineer. The test is usually focused on conditional probability (application of Bayes’ Rule), counting and PDF with various probability distribution (normal distribution, binomial distribution, Poisson distribution etc..). In the interview…

Have you ever been called to participate in jury duty? If you have, doesn’t it seem rather odd how the judicial branch calls upon you, an uninformed citizen, to witness testimonies and reason with freshly perceived information and (sometimes) assumption to ultimately come to a verdict that will impact an…

When exploring a few notebooks that analyse lotteries on Kaggle, I noticed that they mostly focus on interactions and correlations between numbers. However, I haven’t encountered a notebook that would analyse the occurrence of numbers using probability distributions. Therefore, I decided to investigate this by comparing the occurrence of numbers…

An overview of the types of questions in a Data Science interview along with the hands on practice using our platform — In 2012, Harvard Business Review called Data Scientist the sexiest job of the 21st century and the growing trend in the number of job openings for Data Scientist seems to be confirming that statement. With the increase in data, most of the companies today are leveraging Data Science heavily to…

The SOA recently released an interesting mathematical problem for future actuaries to take a crack at solving. Problem Description Our story begins in a park where we turn our attention to a squirrel searching through a plot of grass for fallen acorns. This particular plot of grass is enclosed by sidewalks and…

The Bayes’ rule, also called Bayes’ theorem, describes the probability of an event occuring if another event, the condition, already occured. Notation
