### Online advertising: mathematical formula to compute reach and frequency

Could anyone help me solve these two formulas below using hypothetical numbers?Online Advertising Mathematical FormulaReach = Unique Users - Σ Uk ( 1 - P )kthe sum is over all positive integers k = 1, 2, etc.Uk is the number of users turning exactly k pagesP is the ratio of purchased impressions by total pagesUnique users who see the Ad n times:Σ Uk C(k,n) Pn ( 1 - P )k -the sum is over all positive integers greater or equal to nC(k,n) = k! / [ n! (k-n)! ] are the binomial coefficientsSee More
