Question

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

Answer 1

Count the even and odd integers from 1 to 20

There are 10 even integers from 1 to 20

Also, there are 10 odd integers from 1 to 20.

So, the number of ways to generate a pairing of 10 even and 10 odd integers is given by

`10*10=100`

Therefore, there are 100 different ways for a computer to randomly generate a pairing of an even and an odd

integer out of the numbers 1 through 20.
