Congraduations. There was a 2.2254760097829025399892219575793e+282 : 1 chance of getting the number 91 twice. You have beaten the odds.
I used the windows calculator. BTW I calculated the chance of getting 91 twice, not getting any number twice

I doubt it would be that high. that is greater than 2 with 282 digits after it. look like this:
