Maths problem - statistically speaking...

So I'm sure some of you saw that Facebook meme going around at the beginning of the year - the "52 Week Challenge".



Point is to save a dollar for week 1, 2 dollars for week 2, 3 for week 3 etc... going through the end of the year.



Well in my house we do things different to keep it fresh and exciting - who wants to know in advance that you'll be saving the most money when you're supposed to be spending it, at Christmas?



Instead, we put 52 numbers in a container and pull one out. We have 4 "bye" weeks. If we pull out a bye week, we don't save that week. Maybe buy scratch tickets with it or whatever.



ANYWAY......



My wife did this from the start but in week 1 I did not. I started out intending to do it as the meme stated. So that was my week 1 contribution. All told, so far I've put in:



1-48-20-8-32-and 16 dollars for a total of $125.

SHE put in

20-42-9-23-3-28 for a total of..... yep. $125.



How bizarre is that? Can any stats guys give me the odds on that?





We also have side-games. How close to the actual week is the number you pulled? She pulled a 3 in week 5 for a difference of 2. Gonna be hard to beat, as is our combined 90 dollars in week 2.
