| Abstract: | The paper introduces the random variable of Bernoulli and discusses its basic operational quality. The paper also tempts to use the digital characteristic of the random variable of Bernoulli and different kinds of operational qualities to caculate the expectancy and variance dispersion of some random variables of discrete. |

| Keywords: | probability random variable of Bernoulli expectancy variance dispersion |
