Question

What is the probability that a leap year, selected at random, will contain 53 Saturdays?

• A.
  $\frac{2}{7}$
• B.
  $\frac{3}{7}$
• C.
  $\frac{1}{7}$
• D.
  $\frac{5}{7}$

Answer 1

The correct option is A

$\frac{2}{7}$
Every leap year will have 366 days.
1 leap year = 366 days

$=52\times 7+2days$

Every leap year will have 52 complete weeks. For ${53}^{rd}$ Saturday there are two favourable cases from 7 possible cases.
