The probability of choosing a 31-day month is 7/12. :)
out of 12 months in a year, 7 months have 31 days therefore:
7/12 is the answer
The probability is 58.3 percent
The probability of choosing a month with 31 days is or .
The concept of classical probability can be used to solve the given situation.
The probability of an even to happen is computed by dividing the total considered outcomes by total possible outcomes.List of the months with the corresponding days.
1. January - 31 days
2. February - 28 days or 29 days for Leap Year
3. March - 31 days
4. April - 30 days
5. May - 31 days
6. June - 30 days
7. July - 31 days
8. August - 31 days
9. September - 30 days
10. October - 31 days
11. November - 30 days
12. December - 31 days
Let say the event, , is the probability of selecting a month with 31 days.
There are 7 months which have 31 days and there are 12 months in a year, so the desired probability is the ratio of 31 to 12 or .
Thus, the answer is 58.33%.
