Find the probability of the month of September having 5 Sundays.
Answers
Answer:
We know that
September has 30 days, which means 4 weeks and 2 days.
Now, 4 weeks will contain 4 Sunday.
The remaining 2 days may be :
1. Sunday and Monday
2. Monday and Tuesday
3. Tuesday and Wednesday
4. Wednesday and Thursday
5. Thursday and Friday
6. Friday and Saturday
7. Saturday and Sunday
Total number of possible outcomes = 7
Now, favourable outcomes are : Sunday and Monday, Saturday and Sunday
Number of favourable outcomes = 2
Required probability (P)= Number of favourable outcomes /Total number of possible outcomes
P = 2/7

Answer:
2/7
To find:
the probability of September having 5 Sundays
Solution:
number of days in September = 30 days
number of whole weeks = 7x4 = 2
remaining number of days= 2
there are 7 possible combinations for these remaining two days:
- Monday and Tuesday
- Tuesday Wednesdaysday
- Wednesday and Thursday
- Thursday and Friday
- Friday and Saturday
- Saturday and Sunday
- Sunday and Monday
to find probability:
total number of outcomes= 7
number of outcomes having Sunday = 2
probability = number of favorable outcomes/ total outcomes
probability (Sunday) = 2/7
Hence, the probability of September having 5 Sundays is 2/7.
