Question: what is the probability of getting 54 sundays in a leap year?
Answer: 366/7 = 52.285714… or 52 and 2/7. This means that in a leap year 2 days of the week will appear exactly 53 times, and the other 5 days of the week will appear exactly 52 times. There is no day of the week that will appear 54 times. The probability of 54 Sundays in a leap year is 0.
