392 Views Asked by At

In a $2$ dice throw, one after the other, how many results can there be? Then, if for example we consider the sum of the dice values, how many different ways can we get the sum $7$ with the two dices and in turn what is the probability of having a sum of $7$?

Each dice can be 1...6 so you have $6\cdot6=36$ outcomes.

Sum 7 can come from 1-6, 2-5, 3-4, 4-3, 5-2, 6-1 (6 outcomes)

Probability of having a sum of 7 is $\frac{6}{36}=\frac{1}{6}$
