Two cards are drawn from a well shuffled deck of 52 playing cards with replacement. The probability, that both cards are queens, is
Number of cards = 52
Number of queen = 4
Probability of queen out of 52 cards = 
Now, According to the question,
A deck of card shuffled again with replacement, then
Probability of getting queen is , 4/52
Therefore, The probability , that both cards are queen is , 
Hence, Probability is 
84
