Try this:

select TO_CHAR(DRIVE_DATE,'DAY'),
    count(case when COACH_DRIVE = 'C' then 'C' end),
    count(case when COACH_DRIVE = 'M' then 'M' end)
from blood_drives
where drive_date between '01-jun-2014' and '31-aug-2014'
and coach_drive in ('C','M')
group by TO_CHAR(DRIVE_DATE,'DAY')

This query works perfectly fine.
 Can we add another column totals for each day of the week

>> Can we add another column totals for each day of the week

You can add whatever you want.  Should just be a regular count?

Try this:
select TO_CHAR(DRIVE_DATE,'DAY'),
    count(case when COACH_DRIVE = 'C' then 'C' end),
    count(case when COACH_DRIVE = 'M' then 'M' end),
    count(*)
from blood_drives
where drive_date between '01-jun-2014' and '31-aug-2014'
and coach_drive in ('C','M')
group by TO_CHAR(DRIVE_DATE,'DAY')
