Question 439750: What is the probability that a 31 day month will have 5 Mondays. Assume that there is an equal chance of any one of the seven days being the first day of the month. Show all working. Answer by edjones(7569) (Show Source):
You can put this solution on YOUR website! Any 31 day month whose 1st day is a Saturday, Sunday or Monday has 5 Mondays.
3/7 of 31 day months begin with those 3 days.
3/7 is the probability that a 31 day month will have 5 Mondays.
