Casting two 6-sided dice, there are 36 possible outcomes. For any given number, there is only one occurrence of doubles [1,1 ; 2,2 ; ... 6;6] So the chance of throwing {1 + 1 = 2} is 1/36. And the chance of throwing {6 + 6 = 12} is also 1/36.
If asked what the chance of double-two's that would also be 1/36, but if you ask the chance of rolling a sum of 4, then there are 3 outcomes, which sum to 4 {1+3 ; 3+1; 2+2}, so that chance is 3/36 or 1/12.
The chance of throwing a six with one die is one in six. With a pair of dice it is one in six2 or one in 36.

Let H mean Head and T mean Tail. The outcomes from flipping a coin twice are the same as flipping two coins together. You might get H + H, or H + T, or T + H, or T + T. So there are four possible outcomes. They are each equally likely but if you ask, "What are the chances of throwing H + H" the answer is 1 out of 4 or 25% or 0.25, and the same for throwing T + T. However, if you ask the question, "What is the chance of throwing a H with a T the probability is 2 out of 4 because there are two ways of doing that. So the probability there is 2 out of 4, or 1 out of 2, or 50% or 0.5

(12 ÷ 4) × 2 = 6 2/4th is the same as 1/2 and a half of 12 is 6
(12 ÷ 4) × 2 = 6 2/4th is the same as 1/2 and a half of 12 is 6
(2 + 12) ÷ 2 = 7 Note: mean is the same as average.
