Of the 25 cars sold at a certain dealership yesterday, some had automatic transmission and some had antilock brakes. How many of the cars had automatic transmission but not antilock brakes?
(1) All of the cars that had antilock brakes also had automatic transmission
(2) 2 of the cars had neither automatic transmission nor antilock brakes.
E. the only bits of info you get from the two statements are 1) antilock is a subset of auto transmission and 2) what is not in the union of these two sets. So u cant tell anythign.
