No one has yet calculated the odds but it’s safe to presume that they would be pretty high when you take the following into consideration.
Look at the photo related to this story and then realise that the two men pictured are not identical twins and in fact had never met one another before until they were randomly assigned seats on plane beside each other.
But that is what happened on board a Ryanair flight for Scottish man Neil Thomas Douglas who was sat next to a man who looked exactly like him on a flight on Thursday night.
They even had the same hair cut and beard - even their teeth look scarily similar.
A friend posted a photo of the pair on twitter which was shared thousands of times online.
Social media has been ablaze with people shocked and stunned at the likeness of the strangers.
One said: “That is too weird.”
Another said: “Spooky”
It comes after three Irish college students challenged each other to find their twin strangers (from anywhere in the world) in just 28 days.
Dublin students Niamh Geaney, Terence Manzanga and Harry English used social media to spread their message worldwide.
Within a week, they had hundreds of submissions from all over the globe.
The trio were just a fortnight into the bet when Niamh found a girl who looks almost identical to her, Karen Branigan. Amazingly she was a fellow Ireland native, who lives just an hour away.
