Question 866722
You draw two cards from a standard deck of cards (52 total cards), without replacing the first card before your second draw.  What is the probability that both cards are either a king or a queen?
there are four king and  four queen in deck of 52 cards 
probability for drawing 1 card from 52 card that is king =4/52
 probability for drawing 1 card again with out replacing first card which is queen=4/51
probability for either king or queen will be =4/52+4/51
                                              =4x51+4x52/52x51
                                             =4(52+51)/52x51
                                             =4x103/52x51
                                             =412/2652
                                             =0.1553
answer probability for either king or a queen =0.1553
