In a non leap year, Ist day of the year and last day of year are same.
It means only Ist day of the year is coming 53 times in a non- leap year.

so the probability that a non leap year selected at random has 53 mondays = 1/7
because it is possible to have 53 Mondays in a leap year only if Ist january is a Monday and none any other day of the week.
