If a variable takes value 0,1,2,3,....,n with frequencies `1`,`C_1`,`C_2`,.....,`C_n`

If the variable takes values 0,1,2,…, n with frequencies q^(n),""^(n)C_(1)q^(n-1)p, ""^(n)C_(2)q^(n-2)p^(2), ... ""^(n)C_(n)p^(n), " where " p+q=1 , then the mean is

If the variate takes the values 0,2,4,8..........2^(n) with frequencies ^(n)C_(0),^(n)c_(1),.....^(n)c_(n) and mean is (91times8)/(2^(n)) then n is

A variable takes the values of 0 , 1 , 2 ,....., n with frequencies proportional to the binomial coefficients C_0 , C_1 , C_2 ,......, C_n , then mean of the distribution is (1)   (n(n+1))/4       (2)   n/2       (3)   (n(n-1))/2       (4)   (n(n+1))/2       

Consider the date on x taking the values 0,2,4,8,………., 2^(n) with frequencies ""^(n)C_(0) , ""^(n)C_(1), ""^(n)C_(2),……..,""^(n)C_(n) respectively . If the mean of this data is (728)/(2^(n)) then n is equal to ________.
