The probability of not choosing a green marble is equal to the probability of choosing any other color marble except green.
The total number of marbles in the bag is 2 + 4 + 10 + 9 = 25.
The probability of choosing a green marble is 4/25.
Therefore, the probability of not choosing a green marble is 1 - (4/25) = 21/25.
Converting 21/25 to a percentage gives us 84%.
Therefore, the correct answer is 84%.
