            There is no need to explain that a leap year has 366 days . . .

            If, however, you DON'T KNOW what the "leap year" means, consult this Wikipedia article

            https://en.wikipedia.org/wiki/Leap_year


(a)  The probability P = 1%2F366.


(b)  The probability P = 31%2F366.


(c)  The probability P = 30%2F366.    (June has 30 days, correct ?)


(d)  The probability P = 29%2F366.    (February has 29 days in a leap year . . . )


(e)  Calculate how many days are there in a leap year before May, 1


         31 + 29 + 31 + 30 = 121.


     Therefore, the answer to this question is  121%2F366.

All questions are answered with all needed explanations.

I got the message from you showing that you need to be REMINDED what a leap year is . . .

Honestly, I did not expect to get such a message . . .

Therefore, I placed the reference to Wikipedia article at the beginning of my post, where you can gather the needed knowledge.


Happy learning !
