The remaining 2 days may be
Sunday and Monday
Monday and Tuesday
Tuesday and Wednesday
Wednesday and Thursday

Friday and Saturday
Saturday and Sunday
For having 53 Sundays in a year, one of the remaining 2 days must be a Sunday.

as each leap year comes in 4 years.
So probability of selecting a leap year is 1/4
also probability of sunday in a leap year is 2/7

similarly prob..of normal year in 4 y is 3/4

prob. of sunday in normal year is 1/7

hence total probability =1/4*2/7+3/4*1/7=5/28

Ans 5/28
