Math Problem Statement

A blue dye and a green dye are rolled. Find the probability that the sum is 12.

Solution

To find the probability that the sum of two rolled dice equals 12, we will assume that each dye has 6 sides (a standard die). Here's the step-by-step solution:

1. Possible Outcomes

  • When rolling two dice, each die has 6 faces, giving a total of 6×6=366 \times 6 = 36 possible outcomes.

2. Favorable Outcomes

  • The only way to get a sum of 12 is when both dice show a 6. So, there is only 1 favorable outcome: (6, 6).

3. Probability Calculation

The probability is the ratio of favorable outcomes to the total possible outcomes: P(sum=12)=136P(\text{sum} = 12) = \frac{1}{36}

Thus, the probability that the sum of the two dice is 12 is 136\frac{1}{36}.
