Johnson, this is the solution to the problem:

We have two dice, each labeled 1 to 6.

In consequence, the highest sum after rolling the dices is 12 and the lowest is 2.

For calculating the sample space, we use:

6 (Numbers of the first dice) * 6 (Numbers of the second dice)

Sample space = 6 * 6 = 36

Now, let's find what are the options to have a sum of 4:

• 1 (First dice) + 3 (Second dice)

,

• 2 (First dice) + 2 (Second dice), the order does not matter.

,

• 3 (First dice) + 1 (Second dice)

Therefore, the probability Brandon's roll will have a sum of 4 is:

3/36 or 1/12 (simplfying).
