IF

"It is true that the number of deaths caused by drink is 1000, and it is
true that the number of deaths caused by driving is 2000",

THEN, how can I make any claim regarding the truth of

"It is true that the number of deaths caused by drinking and driving is
...."

Huh? Relevance? :-o


I can't make any claims regarding the truth of "A and B" from the truths
of "A" and "B". Yes?

Sure you can. If -for example- the two sentences

John Jones is an idiot
and
John Jones does not know what he's talking about

are both true, then the "compound" sentence

John Jones is an idiot and John Jones does not know what he's
talking about

is true too.
