I'm looking through my statistics notes and on the page that's giving examples of cases where you can use a binomial distribution it gives the problem:
"The number of red counters in a randomly chosen sample of 30 counters taken from a large number of counters of which 10% are red."
Now my notes goes on to say that this can't be modeled by a binomial distribution but doesn't say how you could model it with any other distribution.
But given that very limited amount of data could you not obtain a reasonable estimate of the probabilities using the binomial distribution as the question states, "a large number" , could we not assume that removing the counter isn't going to change the probability very much?
