According to the give information, our worst scenario you will not get the color which consists of 15 balls is 10-white,12-yellow, 12-black, 14-red,14- blue,14- green total number of balls are 76.Number of balls you pull must be either red,green(or)blue making them 15.So the least n number of balls which satisfy is 76+1=77,Hence solution is completed;Hope you people had fun with this problem thank you::):::::::):::::)::::::)
