find the probability of 53 sundays in a leap year
Read Solution (Total 9)
-
- In a Leap Year, there are 366 Days.
366 Days = 52 Weeks and 2 Days
Thus, a Leap Year has always 52 Sundays.
The Remaining 2 Days can be :
(i) Sunday & Monday ; (ii) Mon & Tue ; (iii) Tue & Wed ; (iv) Wed & Thu ; (v) Thu & Fri ; (vi) Fri & Sat ; (vii) Sat & Sun.
Clearly there are 7 Elementary events associated.
Let A be the event that a Leap Year has 53 Sundays.
Clearly, the event A will happen if the last two days of the leap year are either Sun & Mon or Sat & Sun.
Favourable Outcomes = 2
Required Probability = 2/7. - 10 years agoHelpfull: Yes(30) No(0)
