Step-by-step explanation:
2004 is a leap year
∴ There is 29 days in February, no. 7 days =1 week
∴ 4 week =7×4 days =28 days
∴ 29−28=1 days is remained.
This one day may be {Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday}
If the remaining day is Sunday then there is 5 Sundays in February.
∴ The required probability =
