• A can be born in any of 12 months and B can be born in any of the remaining 11 months ⇒
  
  Total possible cases = 12 x 11 = 132
  
  Total Sample space with us : 12 x 12 = 144
  
  ⇒
  The probability that they are not born in same month = 132/144
  
  ⇒
  The probability that they are born in the same month 1−132/144=12/144⇒1/12
