anjali , can u explain me the first one.
I got the rest.
explanation:
In a leap year there are 52 full weeks i.e 364 days and 2 extra days.
Now these full weeks may start from any of the seven days.
Monday to monday.......... to monday
or tuesday to tuesday...........to tuesday
So, if we want 53 tuesdays, then
either the week should be from monday to monday and first extra day would be then tuesday , probability of this is 1/7
or the week should be from sunday to sunday.. then first extra day would be monday and second extra day would be tuesday... so againg probability would be 1/7 .
then we get 2/7 as the  answer.
