The probability of a non-leap year having 53 Mondays is .........

Options

  1. A2 7
  2. B1 7
  3. C5 7
  4. D6 7

Correct answer

B. 1 7

Step-by-step solution

Number of days in non Leap year =365 aligned & =52 7+1 & =52 weeks +1 day aligned The one additional day may be any one of the day aligned n(A) & =1 n(s) & =7 P ( Getting 53 sundays ) & = n(A) n(S) = 1 7 aligned Hence, option (2) is correct.
