The diagram above shows the sum outcomes of two dice rolls. Notice that there are 36 outcomes and 3 of them are less than 4. Therefore, the remaining 33/36 are greater than or equal to four. This can be reduced to a probability of 11/12.
UPDATE: The grid lines are uneven. If you recreate a 6x6 grid it may be easier to see
