# Weird maths problem ? GCSE watch

1. It says

Jess has a 4 digit password on her phone , each digit from 0 -9 are inclusive

How many choices are possible for each digit ? I chose 10

What is the total number of 4 digit passwords that Jess can create ? 10 000

Jess would like to choose an even number , the code can start at zero . How many different ways are possible now?

I seem not to get what the question is asking me to do , do I have to find the combination of all even numbers or just one ???? Need help I am frustrated

Make it easier. Imagine she can just choose a number from 00 to 19. What proportion of those numbers would be odd and what proportion would be even? Write them all down if you need to.
