OK I've been searching the Web for an answer to a burning question. And finally this page has.. Or almost had an answer!
In a group of 19 people.
What are the odds that....
2 specific pairs of people share the same birthday.
A and B on 1st of Jan C and D on 1st of Feb
AND no one else has a same birthday with anyone else in the group of 19 people...
Lastly. Not sure if this is relevant...
What are the odds that..
Mom has same birthday as daughter in law 1 And dad has same birthday as daughter in law 2.
Or does this not matter in math... As in who's who?
Been trying all sorts of methods but I can't seem to figure out what the odds are.
Like would it be one in a million orrr?
Thanks in advance math whizzes!
