Expert Answer:

Let us assume the worst possible case of drawing different colours one by one 25 times . 
 
When we draw a card at 26th time , we get colour that should match one of the colour previously drawn.
 
Hence minimum number of drawing card is 26 to get atleast two of cards are same colour.
