Poisson Distribution
Now, substitute λ = 10, in the formula, we get P (X =0) = (e – λ λ 0)/0!Two numbers r and s sum up to 8 exactly when the average of the two numbers is \frac{1}{2}*8 = 4 You can also see that the midpoint of r and s corresponds to the axis of symmetry of the parabola represented by the quadratic equation y=x^2BxCBinomial Probability Calculator Use the Binomial Calculator to compute individual and cumulative binomial probabilities For help in using the calculator, read the FrequentlyAsked Questions or review the Sample Problems To learn more about the binomial distribution, go to Stat Trek's tutorial on the binomial distribution
