EArlier I also thought , it should be 1 but more understanding and practising the questions on probability , my concept became clearer.
A leap year has 366 days = 52 *7 + 2 .
So, there are 52 weeks i.e. 52 sundays but the two extra days changes the game.
Now , we have to focus on these 2 days .
The extra 2 days is the main concept to understand = (sunday, monday) , (monday-tuesday) , (tuesday-wednesday) ,(wednesday-thursday) ,(thursday-friday) , (firday-saturday), (saturday-sunday)
If any of the two days is SUNDAY , then total number of favorable outcomes when SUNDAYS are not exactly 52 becomes 2.
Probability of not exactly 52 sundays = 2 / 7
Therefore, Probability of exactly 52 sundays = 1 - 2 /7 = 5/7
Thank you.
