Absolute certainty
First we don't consider leap year There is 1 month with 28 days: february There are 4 months with 30 days: april, june, september, november So the probability to select a month with 28 or 30 days is (1+4)/12 = 5/12 If the year is a leap year then the probability is 4/12
There are 12 months to choose from There are 7 months with 31 days in them. The probability of choosing a 31-day month is 7/12.
The simplistic answer is that August will have five Mondays if the month starts on a Saturday, Sunday or Monday. Three days out of the seven so the probability is 3/7 = 0.4286. However, that assumes that any day of the week is equally likely and that is not the case. The impact of leap years and their 2800-year cycle is to increase the probability to 0.43
It is a certainty. There will always be at least one month that will meet the requirement.
The probability is 1. It is always raining - any time of the day or night, any day of the year - somewhere on Earth.

you wont get your birthday every year
there are 4 monthes that has 30 days each year there are 12 monthes each year. so the probabillity for picking a month that has 30 days in it is 4/12
There are 30 days in a month and 365 days in a year (366 leap year).
There are seven days in a week, 28-31 days in a month, depending on the year and month, and approximately 365.24 days in a year.
The last month of the year is December, which has 31 days.
A long year is 366 days, a long month is 31 days.
February's month is the second of the year.
The simplistic answer is that August will have five Mondays if the month starts on a Saturday, Sunday or Monday. Three days out of the seven so the probability is 3/7 = 0.4286.

JuneThe second month of the year that has 30 days is June.
February is the shortest month of the year
