Answer:
A. 8 green marbles were not chosen
B. 32 green marbles were chosen
C. Not enough information.
Step-by-step explanation:
Data obtained from the question. This include the following:
Green marble = 40
Black marble =..?
A. From the question given, 4/5
of the 40 green marbles were chosen. It therefore means that 1/5 were not chosen.
Green marble not chosen = 1/5 x 40 = 8.
Therefore, 8 green marbles were not chosen.
B. From the question given, 4/5
of the 40 green marbles were chosen.
Green marble chosen = 4/5 x 40 = 32.
Therefore, 32 green marbles were chosen.
C. Not enough information. Since the number of black marbles in the bag was not given, we can not obtain the total number of marbles that were not chosen.
