Of the 25 cars sold at a certain dealership yestarday, some had automatic transmission and some had antilock brakes. How many of the cars had automotive 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
1. no info about automatic transmission supplied cars. there might be 20 cars with antilock brakes and the rest might have only auto transmission. or the other way around...
2. OK. we are left with 23 cars which we do not know what each of them has.
we know that 2 cars do not have either. so there are 23 cars have which have automatic transmission only, antilock brakes only or both so not suff.
E for me
