Multiple same birthdays at work
Here is a chart that shows the likelihood of there being two people at work with the same birthday (day and month), depending on the number of total people.
As you can see, statistically, once the workplace reaches 40 people, the chances have risen to 90%.

In what universe do those stats work out this is the most insane graph I have ever seen. no wonder you vote Liberal. As the saying goes
There are liars, damn liars and statisticians.
at 52 employees you would have a 100% change of a match of a birthday in the same week but not the same day

There are other places that offer similar results. At 52 employees, the chances of the same birthday are 'statistically' 97.36%. On the same day.
No wonder I vote Liberal? Nice insult for good measure. And a happy holiday to you, anonymous.
