green marbles: 7 out of 4 + 5 + 7 = 7/16 odds of choosing a green marble
not blue: 4 red + 7 green out of 16 = 11/16 odds of choosing a non-blue marble

Total number of marbles is 16, out of which 7 are green and non-blue marbles are 11. Hence the probability of choosing a green marble is 7/16 and the probability of choosing a non-blue marble is 11/16.
Shouldn't this question be in the 'Math' section or 'Homework Help' section instead of in 'Words and Wordplay'?
