Permutations, combinations

@ Lunch

NS: That girl is hot. Forgot her name… Her initials are SM I think.
RV: Are you sure?
NS: Not sure, but I have 1/36 chance of getting it right.
Me: Yeah, better than winning a lottery.
NS: 36 or 26 can’t remember.
Me: I think you wanted to say 26, but the probability will be less than that…
RV: ...yeah, since it’s a combination of the 2 letters.
NS: 1/26*1/25
RV and me: Exactly!

We lead a sad life.
