Working out a percentage using sql

I have a table that holds four questions and the values assigned to that question. The value can only be Yes or No.

The results will look something like this Q1) Y, Q2) N, Q3) Y, Q4) Y. How can I get my sql result to display 75%?

At the moment I can only get the count to say 3 Yes and 1 No.

Thank you in advance

What's the table structure?

would simple math not work, how is the "3 Yes and 1 No" returned, if you can add the Y's and N's then do something like divide the returned Y's by the total(Y+N) ? because 3/4 would give you .75, 75%...
