Question 181411
<font face="Times New Roman" size="+2">

These are really all the same problem with different numbers.  I'll show you how to do the first one:



1.A menu has 3 appetizers, 5 salads, 7 entrees, and 4 desserts. How many different meals can be made from this menu?


Pick the appetizer first, you have 3 ways to do that.  Then, for each of those 3 ways to pick the appetizer, there are 5 ways to pick the salad -- so far, 15 ways to go.  Now for each of those 15 ways, there are 7 ways to pick the entree...


See the pattern?


The answer is to be found in the product: *[tex \Large 3 \times 5 \times 7 \times 4]


You can do your own arithmetic.


One thing to remember when you are doing number 4.  Once you have picked a president, then there are only 22 people left to choose from.  Once you have picked a president and a vice-president, there are only 21 people left, and so on.
