why does math hate me? i have a problem with probability questions... i know that i can get a heads or tails - 1/2 but that's it. i have a few math books - i start reading about probability and i get all confused. could someone please explain it to me in very simple terms... i know that (and) means muliply and (or) means addition - but when the problem is written i just don't get how to apply it. any help greatly appreciated!
