What is the chance that a leap year selected at random contains 53 Fridays ?

A. 1/7

B. 3/7

C. 2/7

D. 2/13

Answer : C. 2/7

Explanation:

  • A leap year there are 366 days means 52 weeks and 2 days. so already we have 52 fridays.
  • Now the rest two days can be (sun, mon), (mon,tues), (tues, wed), (wed, thrus), (thrus, fri), (fri, sat), (sat, sun) so, the probability of 53 fridays = 2/7.
