two cards are drawn at random from an ordinary pack of cards . find the probability that they will consist of a king

• Ans:1/221
  if we take the card which is in king card ,Totally 4 kings from 52 cards so,4c2/52c2

• Sample space is 50C2 which is equal to 1326. Events of getting 2 kings out of 4 is 4C2 which is equals to 6. So probability of getting two kings is 6/1326=1/221.

• there are a total of 4 kings , so possible ways to draw 2 cards without a king 48C2.
  the possible no of ways to draw 2 cards both being kings 4C2.
  and the sample space is 52C2.
  so probability = {52C2-(4C2+48C2) }/52C2 .
  and if the question mentions atleast a king, then it would be 1-{48C2/52C2}.

• i think it is (33/221)..
  if one card is king and second card is not a king then probability =( 4c1 * 48c1)/52c2
  if two are kings then probabilty = 4c2/52c2....
  so total probability = ((4 * 48 )+ 6)/1326 = 33/221

  in pack of 52 cards 4 are kings
• 7 years agoHelpfull: Yes(1) No(0)
• 4c2/52c2
  because there will be 4 king from 4 sets of 13 cards there are the fav conditions
  and the total probability is 52 cads and from them we have to get 2 cards

• 4/52--as there are total 4 kings out of 52
• 5 years agoHelpfull: Yes(0) No(0)
