Hey there !
Solution:
Total Number of Balls in the bag = 10 + 16 + 8 = 34 balls
=> Sample Space = 34 balls.
1 ) Probability not being a red ball:
=> Possible events = 16 white balls + 8 green balls
=> Possible Events = 24
=> Probability = 24 / 34 = 12 / 17
b ) Neither Red nor Green:
=> Possible Events = 16 white balls
=> Probability = 16 / 34 = 8 / 17
c ) White or Green :
Possible Events = 16 white + 8 green balls = 24 balls
=> Probability = 24 / 34 = 12 / 17
Hence these are the solutions.
Hope my answer helped !

TOTAL BALLS:- 10 RED+16 WHITES+8GREENS = 34 BALLS
As you said a ball is drawn out of the bag at RANDOM . what is the probability that the drawn will be :-
1 . NOT RED:-
So now total balls =34
balls which are not red= 24
As we know probability = total possibilities ÷ total numbers
so probability of not red ball =24/34=
2. NEITHER RED NOR GREEN :-
It means the ball can be the colour of white .
so now total balls =34
White balls= 16
So probability of white ball= 16/34=
3.WHITE OR GREEN:-
Means the ball can be white or green but not red
So here no. of possibilities are 16+8=24
and the total balls =34
So probability of coming white or green ball =24/34=
