That is, 0 leq p(x) leq 1 for all p(x).

Where, lambda is the mean number of occurrences per unit (time, volume, area etc.) and in binomial terms lambda.Hence the given table represents a discrete probability distribution.This is also called Expected Value.The variance of the discrete distribution X, 2 E(x)2-.To check the second condition, let us find the sum of all probabilities.Practice Calculations, statistics, total of rolling two dice, the mean is, the variance is, the standard deviation.
