Answer:
P(green or red) = 935/2721
P(blue, red, or yellow) = 409/907
P(not brown) = 2236/2721
P(not green) = 2171/2721
Explanation:
Probability in this problem can be represented by the ratio:

We can apply this to the first question:
The probability of choosing a green or red M&M can be represented with:

(Note: '#' means 'number')
We can fill this ratio in with the values given in the table.

This simplifies to:

So, the probability of choosing a green or red M&M is 935/2721.
