Probability of getting sum atlest 3 = 1 - proba of getting 1 and prob of getting 2..
Since two dice rolled so prob of 1 is 0
Prob of sum getting 2 = 1/6*1/6 = 1/36

Prob of getting sum atlst 3 is = 1-1/36
= 35/36

When two identical six-sided dice are rolled, in order for the sum to be less than 5,
the various combinations are (1,1),(1,2),(2,2),(2,1),(1,3),(3,1) - 6 combinations

The total possibilities are 6*6 = 36

Probability(Atleast 5) = 1 - P(Sum less than 5) = $$1 - \frac{6}{36} = \frac{30}{36} = \frac{5}{6}$$

Hence, the probability that the sum of the dice will be atleast 5 is $$\frac{5}{6}$$(Option D)
