Question

what is the probability that an year will have 53 tuesdays

Answer 1

2/7
An year has 52 weeks and 2 days.
So there are 52 Tuesdays for sure.
For remaining two days, possible outcomes are
( Mon,Tue)(Tue,Wed)(Wed,Thus)(Thus,Fri)(Fri,Sat)(Sat,,Sun)
So, number of possible outcomes is 7
Number of favourable outcomes is 2
So, probability is 2/7

Answer 2

Hey,

As one year has 52 weeks and one day.

52 weeks means 52 Sunday to Saturdays.

So for 53 Tuesdays the one day left has to be Tuesday.

Favorable outcome = 1
Total outcome=7( as it can be Sunday to Saturday).

So probability that a year will have 53 Tuesdays= 1/7.

Hope it helps.

Correct me if I am wrong.
