Why does the query return count(*) = 3?

Question

MySQL

SELECT 
  `poll_id`, 
  `user_id`, 
  COUNT(*) as polls_count 
FROM 
  `rel_poll_question_user` 
WHERE 
  (
    `rel_poll_question_user`.`department_type` = 'ask-payroll'
  ) 
GROUP BY 
  `poll_id`, 
  `user_id`

Answer 1

Because there are three elements.

Answer 2

So shouldn't it be 1? Because GROUP BY `poll_id`, `user_id` is 1.

Answer 3

Read about DISTINCT.
