Suppose you roll 2 dice what is the probability of rolling a sum of 5?
4/36 or 1/9
To see this, note that we could have:
1 on first die + 4 on second die
4 on first die + 1 on second die
2 on first die + 3 on second die
3 on first die + 2 on second die
And there are 6 possibilties on the first die and 6 on the second...so the total number of outcomes is just 6 * 6 = 36
So.....(4 posibilities for a five) / (36 total possibilities) = 1/9
First you should probably know how many sides are on a SIX sided die Gabe.....
4/36 or 1/9
To see this, note that we could have:
1 on first die + 4 on second die
4 on first die + 1 on second die
2 on first die + 3 on second die
3 on first die + 2 on second die

So.....(4 posibilities for a five) / (36 total possibilities) = 1/9
