Fast i don't understand how to do number 31 & 32

If we look at the first spinner, we see that there are 4 sections. Each section has an even or an odd number on it. So, the probability that the spinner will land on an even or an odd number is 1.
In the second problem, we see the same spinner. There are four sections and two of those sections have an odd number. So there is a probability of 2/4 that the spinner will land on an odd number.

We need more info then that
