A gambler has 4 coins in his pocket. Two are double-headed, one is double-tailed, and one is normal. The coins cannot be distinguished unless one looks at them. The gambler takes a coin at random, opens her eyes and sees that the upper face of the coin is a head. What is the probability that the lower face is a head?
  • a)
    5/8
  • b)
    4/5
  • c)
    2/3
  • d)
    1/2
Correct answer is option 'B'. Can you explain this answer?

Sample Space: {HH,HH,TT,TH/HT}
There are 5 faces that are heads out of a total 8, so probability is 5/8. Let A be the event that the upper face is a head, and B be the event that the lower face is head.
Pr[A] = Pr[B] = 5/8.
Pr[A∩B] = 2/4 = ½.
Hence option b is correct.
