    1. What does it mean by 'rate'? There are four trip on 2013-10-01. How come the rate is 0.33?
    2. What does it mean by 'unbanned clients'? Does 'driver' count as 'client'?
      Why the rate on '2013-10-03' is 0.50?

    @yajingleo rate = (total cancelled trips)/( total trips)

    1. user with client_Id in the trips table should not be 'banned'
