(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A: Albert survived the plane crash

B: Bill survived the plane crash

C: Cory survived the plane crash

Create the sentence (sentential logic) "at most one of them will survive the plane crash".

2. Relevant equations

3. The attempt at a solution

[tex]

\sim[(A\&B)\vee((B\&C)\vee(C\&A))][/tex]

(In case people use a slightly different notation: ~ = 'negation', v = 'or', & = and)

I think this covers all the cases where they do have two or three survivors. Can anyone see anything wrong with my logic?

Thanks!
