question on how to calculate the probability
I didn't quite get why the probability of rolling 2 dice and getting as a resul 3 it's 2/36 , is it possible to have a Formula for this type of calc ?

The sample space of rolling 2 dice is {(1,1),(1,2),(1,3), ..., (6,4),(6.5),(6,6)}, where (x,y) denotes the first roll has a number "x" and the second roll has a number "y".
There are 36 possible outcomes.
From the elements in the sample space, there are only two possibilities in rolling the dice whose sum is 3, namely (1,2) and (2,1). Hence, the probability is 2/36.
Hope this helps.
