The mean of a binomial probability distribution can be determined by multiplying the sample size times the probability of success.
The probability level for an outcome is the probability that the outcome was at least as extreme as the one that was observed.
The significance of the mean of a probability distribution is that it is the most probably thing to happen. The mean is the average of a set of values. If it is the average of a probability distribution, it is the most probable part.
Dependent probability is the probability of an event which changes according to the outcome of some other event.
It is the probability of an event calculated from repeated trials of an experiment.
