Answer:
it is indeed possible to select a green marble from the bag.
Step-by-step explanation:
To determine whether it's impossible for a green marble to be selected from the bag, we need to calculate the probability of selecting a green marble.
The probability of an event occurring is given by:
Probability
=
Number of favorable outcomes
Total number of outcomes
Probability=
Total number of outcomes
Number of favorable outcomes
In this case, the total number of marbles is 18.
The number of favorable outcomes (selecting a green marble) is 2.
So, the probability of selecting a green marble is:
Probability of green marble
=
2
18
Probability of green marble=
18
2
Probability of green marble
=
1
9
Probability of green marble=
9
1
Since the probability of selecting a green marble is not zero, it is indeed possible to select a green marble from the bag.
