 4h answered Probability of measuring the label of representation in quantum Fourier transformaton 4h comment Probability of measuring the label of representation in quantum Fourier transformaton What does "$\rho > \in \hat{G}$" mean? 6h comment Expectation number of games until A or B wins in 2 consecutive games It seems you interpreted "games" as the sentence "in a single game we roll $2$ dice" suggested. That sentence wasn't consistent with the rest of the question and has since been removed. 6h comment Expectation number of games until A or B wins in 2 consecutive games I think the confusion stems from the sentence "in a single game we roll $2$ dice". That sounds as if you're using "game" synonymously with "roll", but in the rest of the question you seem to be using "game" to mean the entire process until someone wins. If the latter is what you mean, then I think the question would be reasonably clear if you just remove the misleading "in a single game we roll $2$ dice". 6h comment Number of throws required to obtain T-H-H @Rahul: Those are exactly my three equations. You just split the $1$ over the two cases whereas I said the $1$ throw is incurred no matter what its result is so I put it in front and then just added half of the additional throws for each case. 7h comment Number of throws required to obtain T-H-H @Rahul: Thanks for the correction. I fixed the answer. 7h revised Number of throws required to obtain T-H-H correction in response to comment 7h comment Combinatorial proof or meaning of the identity I know it was just a proof idea, but perhaps you can flesh out a detail nevertheless: If the smallest non-singleton set has two elements, it gets split into two singleton sets. But if the partition has singletons, any two singletons could have formed the two-element set that gets split, so many even partitions get mapped to the same odd partition? 9h comment Finding event with specific probability.
