4 - i
Step-by-step explanation:

To test this, we can simply treat 4 and -i as the sides of a right triangle and find the hypotenuse:
So indeed the answer is 4 - i

There are numbers that can be formed.
There are only 100 million valid numbers (). Let the number of valid numbers be n.
Therefore, the probability of picking a number that is valid is:
P(valid) = n / N
