probability that a leap year is chosen at random will have 53 sundays

• A Leap Year has 366 Days which includes 52 complete weeks and 2 odd days..
  As we need the probability of having 53 Sundays, the two odd days may be either Sunday & Monday (or) Saturday & Sunday.. so selecting 2 out of 7 => 2/7

• In a leap year 2 days are extra in a week( 52 Weeks + 2 Days)
  Now this two days can be
  (Sunday,Monday)(Monday,Tuesday)(Tuesday,Wednesday)(Wednesday,Thursday)(Thursday,Friday)(Friday,Saturday)(Saturday,Sunday)
  Hence
  Total No. of Possible outcomes=7
  and Chance of occurance of Sunday =2
  Hence probability= 2/7 Ans.

• A Leap Year has 366 Days which includes 52 complete weeks and 2 odd days,,,,
  the 2 days may be as..
  (Sunday,Monday)(Monday,Tuesday)(Tuesday,Wednesday)(Wednesday,Thursday)(Thursday,Friday); (Friday,Saturday); (Saturday,Sunday)
  for being sunday..the two odd days may be either Sunday & Monday (or) Saturday & Sunday.. so selecting 2 out of 7 => 2/7

• In leap year we have 52 weeks and 2 more days
  So 2 more days can be
  (Sun,Mon),(Mon,Tue),(Tue,Wed),(Wed,Thur),(Thur,Fri),(Fri,Sat),(Sat,Sun).
  To have 53 Sunday (52 weeks have 52 Sundays),we have 2 cases are there in which Sunday is there.
  prob=2/7.

• 2/7.. 364+2 days so 2 days out of 7 days....its 2/7
• 10 years agoHelpfull: Yes(1) No(0)
• 2/7 is right answer
• 10 years agoHelpfull: Yes(1) No(0)
