A bag contains balls of two colours, 3 black and 3 white. What is the smallest number of balls which must be
drawn from the bag, without looking, so that among these there are two of the same colour

• 1st Draw:
  Either White or Black ball (Let say White)
  
  2nd Draw:
  If again White, then 2 is the minimum number of draws to have two balls of same colour. [Local Minima / End of Problem]
  and If Black, then we have to go for 3rd Draw. [Problem Continues]
  
  3rd Draw:
  Either Black or White ball will ensure that we will have two balls of same colour. [No more problem persist]
  
  Solution:
  Minimum number of draws to have two balls of same colour is 2.
  Maximum number of draws to ensure a minimum of two balls of same colour is 3.
  
  Verdict: Question is not well written. Thus creating a confusion.
