How many different ways can a computer randomly generate a pairing of an even integer and an integer less than 7 out of the numbers 1 through 20?

Question

Choices are ;

 

10

 

60
 
20
 
70

Answer 1

There are six integers less than seven: 1,2,3,4,5,6

 

There are 10 integers between 1 and 20 that are even: 2,4,6,8,10,12,14,16,18,20

 

"and" means you multiply, so

 

6 * 10=60
