Answer:

3/4

Step-by-step explanation:

7 blue balls and 2 green balls

so if we take a blue ball and do not put it back into the bag it will become 6 blue balls.

Now we need to find what is the probability of getting a blue ball next .

So our formula will be

= No of Blue balls / Total number of balls(No. of green + No. of Blue balls)

= 6/ 8

3/4( when you simplify it)
