Answer:
The chance will be the same (4/7)
Step-by-step explanation:
Old bag
p(blue)=4/7
New bag
p(blue)=8/14=4/7
The chance will be the same (4/7) since both the red and the blue marbles are doubled at the same time implying that the ration of red to blue still remails the same.
I hope the explanation is clear. If so rate brainliest please
