Let x = the number of nonzero digits in a randomly selected zip code. what are the possible values of x? (note: u. s. domestic zip codes have exactly five digits with at least two nonzero digits.)

Solution: The possible values of x are 2, 3, 4, 5. Hence the option 2,3,4,5 is correct.

Explanation:

We are given that U. S domestic zip-code consists of 5 digits and there zip-codes contains at least 2 non-zero digits. It means we can not see a zip-code with five zero's and a zip-code with four zero's.

Therefore, we can have zip-code containing 2 non-zero digits, 3 non-zero digits, 4 non-zero digits and 5 non-zero digits. Hence the possible values of x are 2,3,4,5
