Question

An experiment consists of rolling two fair dice and adding the dots on the two sides facing up. What is the probability that the sum of the dots is 7 or 11?

Answer 1

If you have fair dice there are 36 different outcomes.
The probability of the dots being a seven is: 6 out of 36
The probability of the dots being an 11 is: 2 out of 36
There are six number sevens and 36 outcomes making it 6:36; there are two number 11 making it 2:36.
