As for family members having the same or nearly the same birthday, I looked up a fun math problem I remember from freshman statistics.Man are you lucky in that department MdW. We have birthdays in February, March, April, May June, July, August, October, and November. That is just my wife, children, grandchildren. Just a crazy thing once I thought about it.
How many people have to be in a room for there to be a 50-50 chance two have the same birthday? FOr it to be almost certain two have the same birthday?
Answer: 23 for the odds to be 50-50. 70 people makes the probability 99.9 percent. I'll let someone else explain why that is.
