How many leap years are occurred?
In the last 400 years (since 1610) there have been 97 leap years. The most recent was 2008.
How many hours are there in 400 years?
A period of 400 years contains 97 leap years. There are 24 hours in one day, 365 days in a regular year and 366 days in a leap year. Therefore, a period of 400 years will contain a total of ((400 - 97) x 24 x 365) + (97 x 24 x 366) = 3506328 hours.
What is the probability that a year selected at random is a leap year with explanation?
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
How many days are in 64 years?
There are 365*64 days plus 16 leap days = 23,376 days. However, if those 64 years span a century that is not divisible by 400 (e.g. 1900, 2100 or 2200), there would be one fewer days. There are no leap days in centuries that are not divisible by 400. The year 2000 was a leap year, but 1800 and 1900 were not, and 2100 and 2200 will not be leap years.
Who many days is in a year?
If the question is "How many days are in a year?" the answer is 365 but if it is a leap year there are 366. Answer:Considering the leap years there are 365.25 days in year. This does not account for the minor correction of haing no leap year in centrury (1800, 1900, 2000) years which are divisible by 400 as well as 4.
