Answer :

Answer: 1/3

 33.3%

Step-by-step explanation:

add all the balls : 4 plus 3 plus 2 you must always find the total in the bag first.

then simply put what you know in a fraction:  3 green balls out of 9 balls  3/9 . this would be the fraction but techers always love when you can simplify this even more. so the answer simplified would be 1/3. t

then to calculate the percentage ,basically the probility you would need to divide 1 by 3.

which is 0.333333..... then times by 100% which is 33.3 %
