How to set it up:
How much fluid ounces of the new mixture? (5 + 11) fluid ounces.
(Amount of alcohol from the 2% solution + amount of alcohol from the 66% solution)= Amount of just the alcohol.

%Alcohol_Mixture=100*(Amount of alcohol)/(Amount of mixture)
Alternatively,
Fraction_as_alcohol=(Amount of alcohol)/(Amount of mixture)

%285%2A%280.02%29%2B11%2A%280.66%29%29%2F%285%2B11%29=F, where F is the fraction of mixture as alcohol.
