On September 11, 2002, the 1st anniversary of the terrorist attack on the World Trade Center, the New York State lottery's daily number came up 9-1-1.
1) What is the probability that the winning numbers match the date on any given day? (Note that for this problem and all other problems, months with only one digit should not place a zero before the digit. In other words, if the date is January 1, then the lotter numbers would be 1-0-1, NOT 0-1-1. In October through December for all dates in which the day has two digits, there is no possible way in which those dates can be picked.)
2) What is the probability of an entire year passing without this happening?
3) What is the probability that the date and winning lottery number match at least once during any year?
4) If every one of the 50 states has a 3 digit lottery, what is the probability that at least one of them will come up 9-1-1 on Sept 11?
Thank you for any help. Explanations are appreciated.
