Properties of Binomial Distribution.

1.	Properties of Binomial Distribution.
Answer» The mean np of the binomial distribution shows the expected number (average) of successes in n Bernoulli trials. The variance of the distribution is = npq. So its standard deviation is = \(\sqrt{npq}\) In the distribution np > npq. Probability of failure q = \(\frac{npq}{np}\) If p < 1/2, skewness of the distribution is positive. If p > 1/2, skewness of the distribution is negative. If p = 1/2, skewness of the distribution is zero and it becomes symmetrical distribution.
