There is a bucket with lots of marbles. Some are red, some
are blue, some are green and some are orange. We don't know
the quantity of any. With your closed eyes how many minimum
number of marbles you will pick so as to 100% sure that
atleast 2 marbles have the same colors.




Answer Posted / murali

Ashish, you are wrong..

there is not guarantee that we pick different colored marble
each time. with your closed eyes , u may pick the same
colored marble each time.

Ankur is right. we need to pick at least max(red , orange ,
blue , green ) + 1 marbles inorder to make sure that
atleast 2 marbles are same color.
