The idea is to help you learn and understand the work, not to just "answer" it for you. If you keep getting people to just answer everything, you'll never have a clue.

And I think it would be a whole lot easier to help if you wouldn't put 8 questions in one thread.

Let's just start with the first one. The jar has red marbles. It doesn't mention anything about blue marbles. If that jar contains red marbles, logically, what do you think the chances are that you're going to pick a blue one?

Second one is the same way. LOOK at the list of numbers. What could possibly be the chances of picking an even number?
