According to me, the best part of the workshop was the 2 x 2 matrix of permutations and combinations of distinct and total objects. As I was introduced to the topic in prior I had some idea but the 2 x 2 matrix made them clearer. Also, we did not leave any problem incomplete that is we did not stop before getting the right answer. Every student was getting personal attention. Thank you Vichar Vatika, I had a great time and had fun. Looking forward to attend more such workshops.
