If two 6-sided number cubes are rolled, what is the probability that you will roll a 1 first and then roll a 5 with the second cube?

The answer is 1/36. This is because there are 36 possible outcomes and this is only one of them. 

If you were to ask what the odds of getting a 1 and a 5, it would be higher, but the fact that they need to come in that order give you the above answer.
