Answer: a) 45 b) 60
Step-by-step explanation:
Given : A small restaurant has a menu with 2 appetizers, 5 main courses, and 3 desserts.
a) Number of meals includes an main course , a dessert and a appetizer, :-
[tex]2\times5\times3=30[/tex]
Number of meals includes an main course and a dessert and but not appetizer , then total possible meals:-
[tex]5\times3=15[/tex]
Then, the number of meals are possible if each includes an main course and a dessert, but may or may not include an appetizer= 30+15=45
b) Number of meals includes an main course and appetizer but not dessert:
[tex]5\times2=10[/tex]
Number of meals includes only main course =5
Now, the number of meals if dessert is also not required= 45+5+10=60
