This is our 4th post in the Cheenta Probability Series that deals with the physics involved in coin tossing. It reveals the true nature of uncertainty. “It is a very tedious task !! First you have to calculate where he is and where is is not, then you must...

This is a very simple and beautiful sample problem from ISI MStat PSB 2013 Problem 7. It is mainly based on simple hypothesis testing of normal variables where it is just modified with a bernoulli random variable. Try it! Problem- ISI MStat PSB 2013 Problem 7 Suppose...

This is a very simple and beautiful sample problem from ISI MStat PSB 2013 Problem 9. It is mainly based on geometric distribution and its expectation . Try it! Problem- ISI MStat PSB 2013 Problem 9 Envelopes are on sale for Rs. 30 each. Each envelope contains exactly...

This is a very beautiful sample problem from ISI MStat PSB 2012 Problem 9, It’s about restricted MLEs, how restricted MLEs are different from the unrestricted ones, if you miss delicacies you may miss the differences too . Try it! But be careful. Problem- ISI...

This is a very elegant sample problem from ISI MStat PSB 2010 Problem 10. It’s mostly based on propertes of uniform, and its behaviour when modified . Try it! Problem- ISI MStat PSB 2010 Problem 10 Let \(X\) be a random variable uniformly distributed over...
