Answer: 7/15
Step-by-step explanation:
1. Most probability questions are asking to find the favourable outcomes over the number of total outcomes.
The favourable outcomes will be green marbles.
There are 7 green marbles, so there are seven favourable outcomes.
There 6 + 7 + 2 = 15 total outcomes.
Thus, there are 7/15 favourable outcomes.
