Answer:
An ordinary year has 365 days.
i.e 52 weeks and 1 extra day.
52 weeks will have 52 sundays.
The sample space for one extra day is
S={MONDAY,TUESDAY,WEDNESDAY,THURSDAY,
FRIDAY,SATURDAY,SUNDAY}
n(s) = 7
Let A be the event that the extra day is a sunday
n(A)= 1
P(A)= n(A)÷n(S)
=1÷7
Therefore the probablity that an ordinary year has 53 sundays is 1÷7.
