You are coming home hungry and look in your fridge. You find: 1 roll and 2 slices of bread, a jar ofpeanut butter, one single serve package each of mayo and mustard, a can of cheezewhiz, some slicedham, and some sliced turkey. How many different types of (edible) sandwiches can you make? Writedown any assumptions (order matters or not, repetitons allowed or not).
