In the pack of 52 cards if person select 3 card randomly find probablity that selection of king, queen, jack??

• ans is 64/22100.
  there are 4 kings,4 queens and 4 jacks in the pack of 52 cards.
  so there are 4*4*4=64 ways of selecting king,queen,jack
  and there are 52c3=22100 ways of selecting 3 cards from 52 cards
  so required probability=4*4*4/52c3=64/22100

• 1 king can be selected from 4 king in 4c1 ,same way from 4 queen 1 can be selected i 4c1 ways and jack can be selected in 4c1 ways ,total ways of selection of 3 cards fom 52 cards is 52c3,so probability=4c1*4c1*4c1/52c3=16/5225 is the answer

• Using formula of nCr
  12C3/52C3 =(12*11*10*9!/(9!*3*2)) * (49! * 3 *2/(52 * 51 * 50 *49!))
  =22/2295
  12C3 because total no. of favourable cards are 12 and we have to pick only 3
  52C3 because total no. of cards are 52 and again only 3 are to be picked.

• ans :16/5525
  
  p(e)=n(q)*n(k)*n(j)=4/52*4/51*4/50*6=16/5525
  
  6 no of ways the kqj can be draw from deck of cards

• probability of getting a king on your first draw is 4/52.
  probability of getting a queen after a king on your second draw 4/51
  jack after a king and a queen 4/50
  So the probability of getting a king, then a jack, and then a queen is (4*4*4)/(50*51*52).=16/5525
  
  There are six orders that give you a king, a queen and a jack.
  
  KQJ, KJQ, QKJ, QJK, JKQ, JQK
  
  So, we take the original probability and multiply it by 6.
  
  6*(4*4*4)/(50*51*52) = 16/5525

• we have 4 of king, queen. and jack so, (4C1 * 4C1 * 4C1)/(52C3)=16/5525
