What are the odds?!

[Blacklab1]

I’ve had two new bank cards recently - different providers.

Both are the ones that have no numbers on the physical cards and you have to get your new pin on the app.

Both pin’s the same!

1/10,000 approximately

Well that’s answered that! Less than winning the lottery then…

With pin numbers there are ten digits and four places so it's 10⁴=10,000(minus the numbers it doesn't allow eg 1111, 1234 etc)
With the lottery there are 59 numbers and six places so it's 59⁶=42180533641

Sorry that not how it works re the lottery

If you take the lottery it’s 59C6 in a scientific calculator.

First bit is 59*58*57… 56 ie with your first choice there are 59 balls to choose from then 58 then 57 etc

But that’s a specific order. It doesn’t matter what order the ‘right’ 6 numbers come out in. The first number can be any of the 6 then there 5 left then 4 etc. so you need to divide by 6! Which is 720

So answer is about 45million to 1

Oh yes of course, you can only use each number once in a lottery, I stand corrected.
