A model is a way of assigning truth values to each proposition. In other words, a model is a possible scenario or situation in which the given propositions could be true or false.
For the first sentence, A & B & C & D, there is only one possible model: all propositions must be true for the sentence to be true. Therefore, there is only one possible way of assigning truth values to the four propositions that makes this sentence true.
For the second sentence, A V B V C, there are 15 possible models. This is because each proposition can be either true or false, and there are 2^3 = 8 possible combinations.
However, since the sentence is true as long as at least one proposition is true, we must subtract the one model where all propositions are false. Therefore, there are 8-1=7 possible combinations of true and false propositions that make this sentence true. Since each proposition can be either true or false, there are 2^4 = 16 possible models.
For the third sentence, A & C, there are two possible models. A and C can either both be true, or both be false. Therefore, there are only two possible ways of assigning truth values to the two propositions that make this sentence true.
In summary, there is only one model for the sentence A & B & C & D, 15 models for the sentence A V B V C, and two models for the sentence A & C.
