We want to make a model for each possible combination of predictors (for example, there would be ten models of just each predictor variable alone, with an intercept). This way, we can see what the best combination of variables is. How many models would we have to create to create every possible model? 

Question text A restaurant offers 3 appetizers, 4 mains, and 2 desserts. Student 1:"I was asked to find how many meals include 1 appetizer and 1 dessert. I did C(3,1) × C(2,1) = 6."Answer 1 Question 44[select: , The student is correct; the multiplicative principle was used properly and the total is 6., The student is incorrect; combinations are not valid here and the correct value is 5., The student is incorrect; additive principle should have been used and the total is 3.] Student 2:"I was asked to find how many full 3-course meals can be made.
