Hello,Curtius!

I think you have miscounted.

But then, maybe I did, too . . . Please check my reasoning and my work.

The originator [1] can tell any of the other people.

. .

[2] can tell any of the other people ... excluding [1].

. .

[3] can tell any of the other people ... excluding [1], but including [2].

. .

[4] can tell any of the other people ... excluding [1], but including [2] and [3].

. .

. . . . . .

can tell any of the other people.

I am not sure what the prob. is for P(r).
