Two identical pack of cards A and B are shuffled throughly. One card is picked from A and shuffled with B. The top card from pack A is turned up.
If this is the Queen of Hearts, what are the chances that the top card in B will be the King of Hearts?

Two comments about the last entry, if the first card taken from A was indeed pulled from the top and the pack was a new one then the likelihood of the it being the king of hearts is higher as they are next to each other when you start, but, the question doesn't say that the card taken fron A was from the top, it just says it was picked from pack A, and it doesn't state that the two packs of cards were new or indeed how or for how long they were shuffled, from the info given only one solution can be possible
