Each die has 6 possible outcomes (the numbers from 1 to 6).
If we roll two dices, the total number of outcomes is 6 * 6 = 36.
From these outcomes, the ones that have a sum of 4 are:
(1, 3), (2, 2) and (3, 1).
So, if we have 3 wanted outcomes from a total of 36, the probability is:
Therefore the correct option is the second one.
