Answer 1

Hey user !!

TOtal no. of outcome= 366 days as a leap year has 366 days ...
Now,, let A be the event of Having 53 fridays in leap year ..
LET P BE THE PROBABILITY..
NOW ,, THE PROBABILITY=The given outcome÷Total no. of outcomes ..
= 53÷366= 0.144
2) Let B be the event having 52 fridays ..
PRobability= The given outcome÷ The total no.of outcomes ..
= 52÷ 366= 0.142
3) Let C be the event having 53 fridays in a non leap year..
Probability= The given outcome÷ The total no. of outcomes = 53÷ 365= 0.145
