Dear Student
Following is the solution of your question
There are 366 days in a leap year which makes 52 weeks and 2 additional days
So 52 weeks makes 52 fridays
aditional 2 days could be MON TUE, TUE WED, WED THURS,THURS FRI, FRI SAT,SAT SUN,SUN MON
so 7 possibilities out of which 5 cases do not have friday so the probability of 52 fridays will be 5/7 .
So check the question if it is asking for 53 fridays as in that case the probility will be 2/7.
Hope it clarifies your doubt
Regards
