If you would not post your questions as an attachment, you would get more and possibly better replies. Many of us do not like to open attachments.

You can learn LaTex to use mathematics publishing on webpages.

Question 1 doesn't make much sense as written. They talk about choosing vowels first, then abandon this and talk about choosing consonants. But I believe your answer is correct.

Your answer to Question 2 seems correct also, although I don't quite know what a "spinner" is supposed to be. A roulette wheel? Anyway, I'd say you're right.

As for Question 4, I'm a little confused by it myself, since I'm not sure what $P$ is supposed to be in the formula. Let me think about it a while.
