What useful tool allows us to refine our previous estimate of the probability of an event given new observations?

1-bayes Theorem
2-The Central Limit Theorem
3-The x-bar chart
4-The Normal Distribution

i think normal distribution but i am not sure!!

If you are sampling from the same population and your estimate of p(x) is (x)/n (n=sample size) then the result of repeated random samples from the population will converge to the population value according to the central limit theorem. The underlying population doesn't need to be normally distributed.

you are right..i must study on this..
thank you very much
