there are 52 cards in a pack one card is missing . Two of the cards are selected at random. Find the probability that missing card is a spade

• as we have to calculate the prob. of missing card, so the statement two cards are selected is not used fpr solving question
  therefore total cases 52
  total flavorable cases 13c1
  prob.= 13c1/52=1/4

• This problem has to be treated as if we are selecting the third card out of 50 remaining cards.
  11 of these cards are spades.
  
  hence probability of missing card is a spade is 11/50.

• There are 52 cards in a pack.one card is missing.so there must be 51 cards.there are 13 cards per shape in a pack.
  the probability of missing card to be spade is 13/52=1/4.

• 13/50 is the right answer
• 9 years agoHelpfull: Yes(1) No(0)
• there is 13 cards in a spade
  and probability missing the card=13C1/52
  1/4
  
  answer is 1/4

• this is just used for making ques tricky it is quite simple 13c1/52c1
• 9 years agoHelpfull: Yes(1) No(0)
• ans :-13c1/52c1
  as there is a question of only finding the probability of missing card

• If we draw 12 spade from remaining 51 cards then it is sure that missing card will be spade..
  So probability of drawing 12 spades from 51 cards is=12/51

• If missing card is spade 12/51
• 9 years agoHelpfull: Yes(1) No(0)
• it will be 13/52 =1/4

• The given second statement has nothing to do with the solution. In a pack of 52 there are 13 each of heart, diamond,club and spade. therefore prob of spade out of 52 cards=13/52=1/4.

• i guess it is
  13c1/52c1
