Correct Answer - Option 1 : 2/7
Concept used:
The leap year has 366 days
Formula used:
Probability = Favourable outcomes/Total number of outcome
Calculation:
The year 2020 is the leap year and has 366 days
Number of full weeks = 364/7 = 52 weeks
And the remaining two days can be,
Sun-Mon, Mon Tue, Tue Wed, Wed Thru, Thru Fri, Fri Sat, Sat Sun
Out of which 2 combinations would give 53 Sundays.
Probability = 2/7
∴ The probability of being 53 Sundays in 2020 is 2/7
