What is the probability of having 5th Sunday in the month of December.

To calculate the probability of having a 5th Sunday in the month of December, we need to consider the number of Sundays and the number of days in December.

1. Determine the number of days in December:

   • December has 31 days.

2. Determine the number of Sundays in December:

   • To find the number of Sundays, we need to determine the day of the week for the 1st day of December.
   • We can use a calendar or a tool to find that December 1st, 2021, falls on a Wednesday.
   • Since there are 7 days in a week, we can calculate the number of Sundays by dividing the remaining days (31 - 1 = 30) by 7.
   • In this case, 30 divided by 7 equals 4 with a remainder of 2. So, there are 4 full weeks and 2 extra days.
   • Therefore, there are 4 Sundays in December.

3. Determine the probability of having a 5th Sunday:

   • Since there are 4 Sundays in December, the probability of having a 5th Sunday is 0.
   • This is because there are not enough Sundays in the month to reach the 5th Sunday.

In conclusion, the probability of having a 5th Sunday in the month of December is 0.
