Badri has 9 pairs of dark Blue socks and 9 pairs of Black socks. He keeps them all in a same bag. If he picks out three socks at random what is the probability he will get a matching pair?

• 100%
  Because, at least two socks will definitely be of same color.

• Let black-BL,blue-BU. Now different possible combinations of three socks are-
  BU BU BU,BU BL BL,BU BL BU,BL BU BU,BL BL BU,BL BL BL,BL BU BL,BU BU BU
  
  Notice that in each case we get a pair of socks.Hence the probability of getting a matching pair is 100%.

• probability is '1' because all combinations may contain atleast 2 same colors

• 100% possibility cannot be there as it is possible that out of three socks all can be of left leg and other possibilities..and they are asking for matching pair.
