There are 4 months that end in the letter Y, January, February, May, and July. The probability, then, of a random month ending in the letter Y is 4 in 12, or 1 in 3, or about 0.3333.
It is 1/6.
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.
It is 1. Every month contains 28 days.
If a 31-day month starts on a Friday, Saturday or Sunday it will have 5 Sundays; if not it will have 4. So the probability is 3/7.
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. Out of those January, February, May, and July end in Y. 4/12 = 1/3 of the time a randomly selected month will end in Y.
1 in 12
1/7
the probability is 3/12 or 1/4
If using the months' names in the English language, it is 1/3.
It is 1/6.
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 probability is approx 15/16.
It's the probability that I will take another breath of air, or the probability that tomorrow will come, or the probability that the moon will go through all its phases for the next month.
It is 1. Every month contains 28 days.
If a 31-day month starts on a Friday, Saturday or Sunday it will have 5 Sundays; if not it will have 4. So the probability is 3/7.
If you assume, incorrectly, that birthdays are distributed uniformly across months, then the answer is 2/12 = 0.166... recurring.
