... geometrical series to compute E[X(X+1)] and then use the identity var(X) = E[X(X+1)] – EX − E(X) 2. A company has 150 employees and wants to install telephone exchange equipment with n lines (connections) outside the company’s building. The higher n, the higher the costs. Assume that at arbitrary mo ...

... an electronic random number generator. 2. Rain. When a weather forecaster makes a prediction such as a 25% chance of rain, this means that when weather conditions are like they are now, rain happens 25% of the time in the long run. 3. Winter. Although acknowledging that there is no law of averages, ...
