Respected sir Sir why do we need so much of calculation for red ball and black ball problem???? let us analyse like this Number of black balls available in the first bag is 4 number of red balls available in the second bag is also 4 4 x 4 is our favourable things so therefore it should be in the numerator because you need to draw a black ball from back one and put it to back to and take red ball from back to therefore 16 is in the numerator what is there in denominator ? now to the 16 add the opposite of it that is 5 x 3=15 Show the answer becomes 16/16 plus 15 that is 16/31 I'm Prof Venkataraiah bangalore

Dear sir for patients Heart Attack problem do we really need to do all these things? Anyway you need to multiply by 1 by 2 and .4 to both numerator and denominator always Is it not .7 /(.7+.75) Will that not give you an answer? Let me explain whether the patient getting in heart attack is 40% are 70% or 90% doesn't matter what actually count is survival of the person when he is doing yoga and when he is taking medicine complement of that will give you answer right? If you want to check correctness of my solution change your 40% to some other % verify the answer

Thank you so much 🙏 for your valuable feedback sir. Actually I was just following the same algorithm that I was using in previous questions of this exercise so that students can easily learn and apply bayes theorem . And also after the end of this question we have discussed the solution that is given by you as a shortcut. Again thank you so sir I really appreciate your valuable feedback 🙏🙏. When you have time please do watch and correct me wherever you think so..I would love that thing..after all I am in learning phase...🙏🙏🙏
