Question

What is the probability of rolling a sum of 5 when rolling 2 dice?

Option A: 1/36

Option B: 1/18

Option C: 1/9

Option D: 5/36
Please explain!!! I don't get this!! Ahhh!

Answer 1

look at your sample space
there are 36 possible outcomes
and the possible outcomes to roll a 5 are
(1,4),(2,3),(3,2), and (4,1)
so there are 4 ways
so 4/36=1=9

Answer 2

So the answer is 1/9?? i am sooo confused!!

Answer 3

yep

Answer 4

The sample space when 2 dices are rolled:

$$ \begin{array}{c|c|c|C|}
&1&2&3&4&5&6 \\ \hline
1 &(1,1)&(1,2)&(1,3)&(1,4)&(1,5)&(1,6)\\ \hline
2 &(2,1)&(2,2)&(2,3)&(2,4)&(2,5)&(2,6)\\ \hline
3 &(3,1)&(3,2)&(3,3)&(3,4)&(3,5)&(3,6)\\ \hline
4 &(4,1)&(4,2)&(4,3)&(4,4)&(4,5)&(4,6)\\ \hline
5 &(5,1)&(5,2)&(5,3)&(5,4)&(5,5)&(5,6)\\ \hline
6 &(6,1)&(6,2)&(6,3)&(6,4)&(6,5)&(6,6)\\ \hline
\end{array}$$
