Two cards have been taken from the 52 cards with out replacement. what is the probability that 1 card is red and another card is king?

Hi Vinotha
Since the cards are drawn without replacement, the total number of ways of withdrawing 2 cards would be 52C2
Now there are 26 red cards which also contain 2 kings. There are 2 other kings. So our desired sample space consists of these 28 cards. So the required probability would be 28C2/52C2.
Hope that helps.
