Hi,
I have got following question which i cant solve:
A diner serves a lunch special, consisting of soup or salad, a sandwich, coffee or tea and a dessert. If the menu lists 3 soups , 2 salads, 7 sandwiches and 8 desserts, how many different lunches can you choose?
My solution is:
Sandwiches = 7
Deserts = 8
The above two are without 'or' so their combinations = 56.
Combining 2 Salads = 56 * 2 = 112
or Combining 3 soups = 56 * 3 = 168
Total = 112 + 168 = 280
but answer is wrong. Some body please guide me.
