  1. The die has six sides, equally likely.
    Two of the six are yes values.
    So the probability of a yes is 2/6 or 1/3
    So if you roll 60 times, the mean result should be 20 out of 60 if the die is fair.

    Now we could do a binomial or more likely a normal distribution for n = 60 to figure the probabilities of less than 18 or whatever :)

  2. so my final answer would be 1/3 right? it seems too simple to be true...

  4. the mean of the sample should be the same as the mean of the population.
