+333 In how many ways can a President and a Vice-President be chosen from a group of 5 people (assuming that the President and the Vice-President cannot be the same person)?
+678 There are 5 choices for the president and 4 choices for the vice-president (since there has already been someone chosen for the president).
Once you multiply 5 \(\times\) 4 = \(\boxed {20}\)
