I have a poll with votes from users. For example:

Do you want a Fiat?

```
id | answer
1    yes
2    no 
3    yes
...
25   no

count = 20 yes / 5 no

(20 * 100) /25 = 80% Yes
(5 * 100) /25 = 20% No

```

So, 80% want a Fiat, and 20% don't want. Obviously I can do something like:

```
select answer, count(*) as total from fast_survey group by answer;

```

However this will show the count and I am looking for the relative percentage. Any idea how can I do that?
