From statement 1:
Red + Blue + Green = 17
Since, this ensures that there are at least 3 green marbles, so, remaining marbles must be red and blue.
Red + Blue = 17 - 3 = 14
Blue = 14 - Red = 14 - 8 = 6
But, this doesn't give us the total number of green marbles. So, statement 1 alone is not sufficient.
From statement 2:
Red + Blue + Green = 19
Since, this ensures that there are at least 2 red marbles, so, remaining marbles must be blue and green
Blue + Green = 19 - 2 = 17
Again, Green = 17 - Blue = 17 - 8 = 9.
Hence, statement 2 alone is sufficient to answer the question
