Answer:
35 quizzes
Step-by-step explanation:
We need to determine how many ways we can choose 4 questions out of 7 to make the quizzes.
We do this by using the formula which describes the number of ways we can choose
objects given
possible choices. So, if
and
, then:
Hence, the teacher can make 35 different geometry quizzes.
