3/7
Explanation:
October has 31 days. First 28 days will have 4 Sundays. Now the the last 3 days could be any of the 7 remaining days of the week. If 29th day is either friday, saturday or sunday then there will be 5 sundays in the month, otherwise it will stay 4.
P(5 Sundays) = P(29th day is Fri/Sat/Sun)=
