What is the probability that an ordinary year has 53 Sundays?

Answer»

Given: an ordinary year which includes 52 weeks and one day 

Formula: P(E) = \(\frac{favourable \ outcomes}{total \ possible \ outcomes}\)

so, we have to determine the probability of that one day being Sunday 

Total number of possible outcomes are 7 

Therefore n(S)=7 

E= {M, T, W, T, F, S, SU} 

n(E) = 1

P(E) = \(\frac{n(E)}{n(S)}\) 

P(E) = \(\frac{1}{7}\)
