comment Probability of random shuffling of cards
Thanks. The second case(the interesting one) is the one I am working on. Got the intuition. Would work towards the proof.

Yes and thanks for persisting with me. Can I move this to chat. I have already got an alert!

I would put the 7C back in place of 6S. If 6S is the 32nd card, then after the first replacement 7C would be the 32nd card and 6S the first card (both would swap places). But 6S could be anywhere in the deck.

@GerryMyerson For the first card (7C), I pick any card from the remaining 51 cards (6S). Now I am going to put the original card (7C) back in the deck. And for the next card (6D), I am going to select from the remaining 50 cards excluding 6S and 6D and so on. So what is the probability that 6S,6D,7C or any other card would end up in the list and is it same for all the cards in the pack?

@GerryMyerson Cards once replaced aren't put back. Its a biased shuffle (shuffle may be the wrong term). So for the first card I pick from the next 51 cards, for the second card, I leave the first card and select from the remaining 50 cards and so on. So there would be no selection for the last card since it is automatically select. And just 2 options for the 51 st card.

@RossMilikan The first card can be selected in 1/51 ways, the second in 1/50 ways and so on. But I can't think beyond it as to what's the chance of each card being anywhere in the shuffled deck

Thanks for the suggestion on Binomial Distribution. Regarding Q No.4, if I calculate the average percentage score of all students in the test taken together, does Q have an impact? Regarding Q No.6, can you provide the link to the article.

For question No.6, I changed my simulation and got the results as expected, both strategies yielded the same results.
