Hi, I've shown the problems and the work in the word document. Please see if my answers are incorrect or correct. Please let me know!! Also, the last problem is kinda wierd to me. Could someone explain it to me. TIA!! this probability and stuff was in my discrete math book.
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.
Your answer to Question 3 is correct.
As for Question 4, I'm a little confused by it myself, since I'm not sure what is supposed to be in the formula. Let me think about it a while.
