Those are completely straightforward problems.
So where are you having difficulties?
Do you know the rules and/or the definitions involved?
I'm sure that for you they are completely straightforward and you do not have any problems with solving them. However, I posted it, simply because I don't understand it at all. What would be the point of posting thread which I can solve?
I don't know the rules, probability it's just one of those things that don't come into my head and I can't understand them...
I'm sorry if I've disappointed you by NOT KNOWING the answer for this completly straightforward problem.
