How can I calculate the percentage considering a third factor? Immagine that two schools have voted. In the first there are 330 candidates, the total votes are 1400 and the winner get 120 votes. In the second school there are 150 candidates, the total votes are 900 and the winner get 44 votes. How could you calculate the percentage of each winner considering not only the rate between votes of winner and Total votes but number of candidates too. Thanks in advance.
