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
Read Solution (Total 13)
-
- 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 - 10 years agoHelpfull: Yes(15) No(3)
- 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. - 10 years agoHelpfull: Yes(4) No(5)
- 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. - 10 years agoHelpfull: Yes(2) No(1)
- 13/50 is the right answer

- 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
- 10 years agoHelpfull: Yes(1) No(0)
- ans :-13c1/52c1
as there is a question of only finding the probability of missing card - 10 years agoHelpfull: Yes(1) No(0)
- 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 - 9 years agoHelpfull: Yes(1) No(0)
- If missing card is spade 12/51
- 9 years agoHelpfull: Yes(1) No(0)
- it will be 13/52 =1/4
- 10 years agoHelpfull: Yes(0) No(0)
- 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
- 10 years agoHelpfull: Yes(0) No(0)
- Assume that missing card and other card is also spade..so,13/52
