Question

Suppose you roll 2 dice. Find the probability of rolling a sum of 7.

Answer 1

1 out of 12

Answer 2

because there are a possible of 6 on each dice, so in all it would be 12 because 6+6, so it would be 1 out of 12

Answer 3

welcome to open study (:

Answer 4

Here are the possibilities for two dice to equal 7:
$$
\begin{matrix}
6&1\\
1&6\\
5&2\\
2&5\\
4&3\\
3&4
\end{matrix}
$$
There are 6*6=36 possible outcomes, but only 6 ways to get an outcome that equals 7, so your probability is
$$
{6\over36}={1\over6}
$$

Answer 5

It is 1/12
