Question
What is the probability that an ordinary year has 53 sundays?
✓

Answer

Since in an ordinary year there are 52 weeks and one day.
so, we have to determine the probability of that one day being sunday.
$\text{S} = \big\{\text{M, T, W, T, H, F, S, S, U}\big\}$
$\therefore\text{p(E)}=\frac{1}{7} $
