P (blue, blue) is 2/14, which simplifies to 1/7.
If only one marble was being picked, the probability would have obviously been 4/14. Since the first picked marble was placed back into the bag and the chances are the same for a second blue one, I think all you have to do is halve the probability to produce 2/14.
-6/8
The slope formula is m=(y2-y1)/(x2-x1)
I did this in first grade so easy but.. whatever, okay so first you would need to add 36, 28, and 24 which is 88. Then 88 divided by 11= 8 pieces of fruit per bag.
