What is the probability of getting a queen or spade from a set of cards?

• no. of spade = 13
  no. of queen = 3 (excluding queen of spade)
  no. of possible outcome = 13+3 = 16
  probability = no. of favorable outcome/ total possible outcomes = 16/52 = 4/13
• 10 years agoHelpfull: Yes(39) No(4)
• total cards=52
  no. of spade=13
  so, probability of spade=13/52
  no. of queen(total)=4
  so,prob. of queen=4/52
  Now, as 1 queen will be chosen from spade i.e. it will be common=1/52
  
  therefore,using formula..P(AUB)=P(A)+P(B)-P(AUB)
  putting values
  P(AUB)=13/52+4/52-1/52 =16/52 or 4/13.

• there are 13 spades and 4 queen so 13+4/52=17/52
• 10 years agoHelpfull: Yes(2) No(17)
• total cards=52
  spades=13
  queen=4
  but,one queen is included in spade..so queen=3
  required probability=(13+3)/52=16/52=4/13

• its 4/13..probability of getting queen is 4/52 and probability of getting spade is 13/52 but spade queen has been included so its 12/52
  ans:-12/52+4/52=16/52=4/13

• spade=13
  queen=3
  probability=3/52+13/52=16/52
  =4/13
• 10 years agoHelpfull: Yes(1) No(0)
• SPADE=13/52
  QUEEN EXCEPT IN SPADE=3/52
  =(13/52)+(3/52)
  =16/52
  =4/13

• 4/52 will be the answer..

• no of spade= 13
  no of queens left= 3(excluding the queen of spades)
  probability=16/52 =4/13
• 10 years agoHelpfull: Yes(0) No(0)
• it will be 16/52

• getting a queen in 4 ways and a spade in 13 ways since we have chosen the queen of spade
  reqd prob=4+12/52
  =16/52=4/13

• Total queens r 4 out of which one is spade.
  Nd total spades r 13 out of which one is queen
  So total cards dat r either queen or spade are=13+4-1
  So probability=16/52

• spade includes queen of spade so if we count 13 spades then we must count remaining 3 queens 13/52+3/52=16/52
• 10 years agoHelpfull: Yes(0) No(0)
• There are 4 queens in the 52 cards.
  There are 13 cards in spades(Including 1 queen).
  So we can select 4 queens or 12 spades excluding queen from 13 spades.
  so 12+4=16
  total probability is 16/52= 4/13

• Probability of getting a Queen,P(a)=4/52
  Probability of getting a Spade,P(b)=13/52
  Common case: 1/52 (Queen of Spade)
  ans: (4/52)+(13/52)-(1/52)=4/13
• 10 years agoHelpfull: Yes(0) No(0)
• probability of getting spade=(13/52)
  probability of getting queen=(3/52) already a spade queen taken above.
  so the total probability =(13/52)+(3/52)=(16/52)
