Find the probability that a leap year selected at random will have 53 Sundays
Pick:
A) 6/7	B) 5/7	C) 4/7	D) 3/7	E) 2/7
There are 366 days in a leap year: 52 weeks and 2 more days. So, 52 Sundays and 2 days.   These 2 days can be: {Mon, Tue}, {Tue, Wed}, {Wed, Thu}, {Thu, Fri}, {Fri, Sat}, {Sat, Sun} and {Sun, Mon} (7 cases). In order to have 53 Sundays we should have either {Sat, Sun} or {Sun, Mon} case.   The probability of that is 2/7.   Answer: 2/7.
