would you need to generate/observe a number of random dice rolls to work out the mean and standard deviation
You just mentioned the mean. Since you're measuring "Yes or no, did I roll doubles," this is a binomial distribution. The variance of a binomial distribution is np(1p), where n is the number of trials and p is the probability of success (p = 1/6 here).
For the rest of the nitty gritty, I'll refer you to: http://en.wikipedia.org/wiki/Binomial_proportion_confidence_interval
