Was 1957 a leap year?
No. Leap Years are always even-numbered, because they are always a multiple of four. Since no odd number is a multiple of four, there are no odd-numbered years that are leap years. Since 1959 is an odd number, it cannot be a leap year.

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

Will the year 2022 be a leap year?
no leap years are every 4 years, where the number of the year is a multiple of 4 meaning 2016 and 2020 will be leap years. The exception to this rule being years ending in 00, these are leap years only if the preceding numbers form a multiple of 4. ie.1700,1800,1900,2100,2200,2300,2500, etc are NOT leap years but 1600,2000,2400,2800,etc are How to remember Leap Years: American presidential elections and Summer Olympics.
How many days are in 20000 years?
There are 365 days in a standard year, and 366 days in a leap year. To calculate the number of days in 20,000 years, you would need to account for the leap years within that time period. In general, you can estimate that on average, there is roughly one leap year (366 days) for every four years. So, you could calculate the number of leap years and standard years within the 20,000-year period. 20,000 years / 4 = 5,000 leap years The remaining years (20,000 years - 5,000 leap years) are standard years. So, there are 20,000 - 5,000 = 15,000 standard years. Now, you can calculate the total number of days: 5,000 leap years * 366 days/leap year + 15,000 standard years * 365 days/year = Total number of days (5,000 * 366) + (15,000 * 365) = Total number of days 1,830,000 + 5,475,000 = 7,305,000 days So, there are approximately 7,305,000 days in 20,000 years, taking into account the variation between standard and leap years.
