Normal year has 52 weeks (365/7) + 1 extra day ie. 52 Sundays + 1 day which can be any of the seven days So probability of 53 Sundays === Probability of that day being a sunday = 1/7
OR
The year MUST start on a Sunday, so you have only one favorable chance out of a total of 7 possibilities - a probability of 1/7.

Total number of days in a leep year = 366
Total number of complete week in leap year = 52
Remaining days = 2
They would be ,
Mon, Tue
Tue, Wed
Wed, Thu
Thu, Fri
Fri, Sat
Sat, Sun
Sun, Mon
Total number of outcome = 7
Total number required outcome =2
Therefore, Required Probablity = 2/7.....!!!!.....

So, let us calculate the no. of weeks in an non leap year(it is the same for a leap year, but we actually want the remainder as we will see later)

this means that there are 52 weeks(and hence 52 Sundays) in a non leap year and one extra day. Out of seven days, the probability that that extra day is Sunday=(no.of Sundays in a week)/Total no of days in the week
=1/7
Hence, the probability that a non leap year has 53 Sundays is 1/7
- -5
number of days in a non-leap year=365 days = 52 weeks and 1 day
Each week there is 1 Sunday , but here there is 1 day extra
That 1 day can be either{Sunday, monday, Tuesday, Wednesday, Thursday, Friday, Saturday}
Therefore,Probability of getting that day a Sunday=1/7
Thus,Probability of getting 52 Sundays= 1,whereas getting 53 Sundays =1/7
HOPE IT HELPED YOU
THUMBS UP PLEASE...

i.e 52weeks and 2days
Therefore, Sunday comes 52 times and 2 days is chance of probability
These two days can be either the following (sample space):
Sunday, Monday
Monday, Tuesday
Tuesday, Wednesday
Wednesday, Thursday
Thursday, Friday
Friday, Saturday
Saturday, Sunday
n(s):- 7
We saw that "Sunday" comes twice. So,
P(getting Sunday):- 2/7
GIVE IT A THUMBS UP GUYS!!!

It’s 1/7.
In any year,there’re atleast 52 weeks which accounts for 52*7=364 days.Now a non-leap year has 365 days i.e. 1 day extra.For this day possibilities will be {mon ,tue, wed, thu, fri, sat, sun}.
Thus total no. Of possibilities are 7,out of which there’s one possibility of getting 53 Sundays i.e. when the extra day is Sunday.
Now,
probability =total no. Of favourable outcomes/total possible outcomes
So,probability=1/7.

366 days = 52 weeks alnd 2 days
So there are 53 sundays in leap year
Remaining 2 days can be-
1)sunday and monday
2)monday and tuesday
3)tuesday and wednesday
4)wednesday and thursday
5)thursday and friday
6)friday and saturday
7)saturday and sunday
So;no. Of events= 7
No.of favourable events=2
P(E)= 2/7

OR
The year MUST start on a Sunday, so you have only one favorable chance out of a total of 7 possibilities - a probability of 1/7.
