Answer 6

Have you considered looking up some basic formulas about probabilities? This should help you with these kind of questions. Again, I think it is a better idea to ask a new question in a new post, not as a reply to a former question. If my reply satisfied please consider marking it as best response and closing this question. The same thing counts for your former question about tossing coins.
