Q:

Two cards are drawn at random from a well - shuffled pack of 52 cards. what is the probability that either both are red or both are queens?

A) 17/112 B) 55/221
C) 55/121 D) 33/221
 
Answer & Explanation Answer: B) 55/221

Explanation:

n(S) = C252 = 1326

 

 Let  A = event of getting both red cards

 

and B = event of getting both queens

 

then AB = event of getting two red queens

 

n(A) = C226 = 325,   n(B) = C24 = 6

 

 n(AB)=C22=1

 

  PA=3251326, PB = 61326

 

 PAB=11326

 

P ( both red or both queens) = PAB

 

PA+PB-PAB=3251326+1221-11326=55221

A) 350 kms B) 450 kms
