Abag contains 16 green marbles, 12 red marbles, 15 white marbles, and 7 black marbles. what is the probability of drawing a green marble out of the bag?

The probability of drawing a green marble will be found as follows:

1. First, find your total number of outcomes by adding together all of the types of marbles to find the total you might draw from the bag so that you may make this a proportion. Now, you get your type of marble you want to know the probability of, and you put the total number of green marbles over this number. The total number of possibilities is 50, and the number of green marbles is 16. 

2. I'm not sure what type of answer you are looking for, but the following answers could be the following:
- 16/50
- 32%
-.32

Hope this helps.
