You are guaranteed to have Sundays in a leap year, so in probability terms that is 1.
100%
The year MUST start on a Sunday. For a leap year, it can start on Saturday or Sunday. In any period of 400 years there are 303 non-leap years, of which 43 begins and ends with a Sunday, and there are 97 leap years, of which 28 begins with a Saturday or a Sunday. So the probability in a non-leap year is 43/303, or 14.2%. And the probability in a leap year is 28/97, or 28.9%
A leap year is 52 weeks plus 2 days. That means that 2 days have 53 instances. So there is a 2/7 chance that there will be 53 Fridays. There is absolutely no chance that there are 54 Sundays, since 53 is the most you can have. Good luck. The exact probability is 28/97, which is about 28.87%.
No.
There are either 52 or 53 Sundays in a leap year, depending on which day of the week it starts. If it starts on a Sunday or on a Saturday, there will be 53 Sundays, otherwise there are 52.
probability = 2/7 to be exact, 28/97 (about 28.87%)
The probability is very close to 0.25 A year is a leap year if the number is divisible by 4 - except if the number is divisible by 100 it is not a leap year - except if the number is divisible by 400 it is a leap year. So, in a 400-year period there are 97 leap years. The probability or relative frequency of leap years is, therefore, 97/400 = 0.2425
The total number of days in a leap year is 366. Then, if we want to determine the probability of 53 Wednesdays occurring in a leap year, we write 53 / 366.
There are usually 52 Sundays in a year. But if the year starts on Sunday or is a leap year starting on Saturday, there will be 53 Sundays in that year.
A Leap year has 366 days. in which you have 52 weeks and 2 days. the 2 days may be sun,Mon mon,Tue tue,wed wed,THu, thu,Fri FRi,SAT sat,sun so you have 7 options among which 2 u can choose.. so the answer is 2/7 for having 53 Sundays. The probability of having 53 Thursdays is also 2/7. The probability of having either 53 Sundays or 53 Thursdays is 4/7.
There are always 4 Sundays in February, except if it is a leap year and the 1st of February is a Sunday. In that case there are 5 Sundays.
1896, which was a leap year that began on a Wednesday and ended on a Thursday, had 52 Sundays.
