QUESTION IS NOT FRAMED PROPERLY...WE CAN NEVER BE SURE ON THIS FROM PROBABILITY
POINT OF VIEW.WE CAN ONLY SAY THAT IT IS SOME 60% OR 20% OR....ETC..PROBABLE.
IF WE TALK THEORETICALLY,
IF WE ARE LUCKY MINIMUM OF 3 SHOULD DO TO GET 3 DIFFERENT COLORS
AND IF WE ARE UNLUCKY MAXIMUM OF 8+4+1=13 ARE NEEDED TO GET ALL 3 COLORS.
SO WE MAY NEED ANY WHERE BETWEEN 3 TO 13 CHANCES TO GET ALL 3 COLOURS
BUT THEIR PROBABILITIES DIFFER.13 IS A CERTAINITY..100% PROBABLE
3 IS A RARE OCCURRENCE
