What is the probability that a leap year has 53 Sundays and 53 Mondays?



Answer -

Given: A leap year which includes 52 weeks and two days
By using the formula,
P (E) = favourable outcomes / total possible outcomes
So, we now have to determine the probability of that remaining two days is Sunday and Monday
S = {MT, TW, WT, TF, FS, SSu, SuM}
n (S) = 7
E= {SuM}
n (E) = 1
P (E) = n (E) / n (S)
= 1 / 7
