We will see that there are 50,000 different possible codes that start with an even number.
<h3>
How many possible codes are there?</h3>
We know that the code has 5 digits, each one with 10 possible options (except the first one, when we only can use even digits, so there we have 5 options).
And the numbers can be repeated any number of times through the code, then the total number of different codes that can be made is equal to the product between the numbers of options for each of the digits, we will have:
So there are 50,000 different codes.

Part A)
A mixed number is in the form where W is any whole number part. The p and q are also whole numbers, which when combined together, form the fractional part p/q
To have a mixed number between 3 and 4, we must make the whole part W equal to 3. The p and q can be anything you want as long as p is smaller than q, this is so p/q is a fraction smaller than 1. So for example, we could have p = 2 and q = 7. So the mixed number is one example of a value between 3 and 4.
====================================================
Part B)
This seems to be asking the same exact thing as part A. I'll give another example. The mixed number is between 3 and 4. Again notice the whole part is W = 3. The other two pieces are p = 4 and q = 9. We have p smaller than q.
