Question

The probability that there will be 53 Sundays in a leap year is

• A. 1/7
• B. 3/7
• C. 2/7
• D. ½

Answer 1

Answer: (C)

2/7

Answer 2

1 leap year = 366 days

= 52 week + 2 days.

The possible ways for 2 days are,

S = {(sun, Mon), (Mon, Tue), (Tue, Wed), (Wed, Thu), (Thu, Fri), (Fri, Sat), (Sat, Sun)}

P(5) = $\frac { 2 } { 7 }$
