find the probability that the year chosen at random has 53 mondays ?

1) 5/28
2) 3/28
3) 1/28
4) 2/28

• probability for leap yr is 1 out of 4, i.e 1/4 and non leap yr is 3/4.
  now, non leap yr has 365 days, which gives 1/7 for monday,
  whereas leap yr has 366 days, which gives 2/7 for monday,
  
  so this gives us : 1/7 x 3/4 + 2/7 x 1/4 = 5/28
