The probability that a non-leap year contains 53 Sunday is

Options

  1. A1 7
  2. B1 9
  3. C2 7
  4. D1 5

Correct answer

A. 1 7

Step-by-step solution

A non-leap year contains 365 days and there are total 52 weeks and 1 day in a non-leap year. Hence there should be 52 Sunday also. But the 1 extra day apart from those 52 weeks may be either Monday, Tuesday, Wednesday, Thursday, Friday, Saturday or a Sunday. Clearly, total possible events are =7 and Number of favourable events =1 Hence probability = 1 7
