This is another blog of the Cheenta Probability Series. Let's give a formal definition of statistical regularity to bring some seriousness into account. **10 min read** “The Law of Statistical Regularity formulated in the mathematical theory of probability lays down that a moderately large number of items chosen at random from a very large group […]
This is a very beautiful sample problem from ISI MStat PSB 2012 Problem 5 based on the Application of Central Limit Theorem.

How to prepare for the first level of real Math Olympiads in India (the IOQM)? In this post we discuss books, learning strategies and other tools.
In 2023, 23 Cheenta students (20 current students and 3 ex-students) qualified in IOQM 2023. This is a result of a lot of hard work over several months. Most of these kids regularly attended the five-days-a-week problem solving sessions apart from concept class + homework class + doubt clearing class.
Cheenta is offering a 36-hour program on AMC 10 & 12. In this short review course, we will cover concepts from Number Theory, Geometry, Algebra, and Combinatorics. This course is problem-driven in nature, in the sense concepts will be introduced and taught using relevant problems. Schedule The program starts on September 9th. The online live […]
