Remember that n is the figure of independent trials and p is the likelihood of success.
For small p and small n, the binomial
distribution is what we name as skewed
right. That is, the mass of the probability falls in the smaller
numbers 0, 1, 2... and the distribution falls away to the right. While,
for large p and small n, the binomial distribution is what we know as skewed left. That is, the mass of the probability falls in the larger
numbers n, n−1,n−2,... and the distribution falls away to the left.
