Sorry, I thought you were asking about the 2nd part as you'd written the answer for the first part
Draw a venn diagram for the sets Biology and Chemistry. To find the percentage that do either Chemistry or Biology
50% Chemistry
30% Biology
10% Both (overlap)
If you simply add Chemistry and Biology, is this right, if not how do you correct it?

I'm trying to get you to approach the problem. Have you drawn a venn diagram for the two sets, if not, try doing it. It makes the numbers clear.

The first example in
https://www.ck12.org/probability/ven...bility-ALG-II/
is something like what you want. Have a think about how your problem maps onto it, what is similar, what is different.

What do you understand about the problem? Its relatively straightforward.
* What outcomes are there?
* What is the probability of each outcome?
* What is the expected value?

Try starting to answer the 3 points in post 13, I do know which question we're talking about.
If you don't understand what the possible outcomes are, simply guiding you through this question won't help in the long run.
