The probability of having 50 Sundays in a year is very low. In a standard year with 365 days, there are 52 weeks and 1 extra day, while leap years have 366 days, equating to 1 extra day. For 50 Sundays, a year would need extra Sundays beyond the standard count, which is not possible without changing the calendar system.
