Consider the following image
There is a mine present in each of the three red sections.
Also, there will be two more mines adjacent to the bottom '2'. This makes 5 in total.
Hence, each of the green sections should be free of mines.
Bonus: If there were a mine in the square below the '3' and a mine in one of the two squares to the right of the '4' (in the red L-shape), then it would be impossible to determine which of these two squares contains the mine. I think this is most likely scenario as there seems to be enough information elsewhere.
