Ok here it goes...

suppose certain account numbers are to consist of two letters using letters from the set L={a,b,c,d} followed by three digits from the set N={1,2,3,4,5} and then three more letters from L, where repetitions of letters or digits are not allowed within any of the three groups, but the last group of letters may contain one or both of those used in the first group. How many such account numbers are possible?

thanks in advance for sombodys help, anybodys help...

Im not looking for a sabby emotional story about how you love your puppy and he loves you back. Is there any scientific evidence to suggests that animals are capable of loving something. I find it hard to believe that they do, evolutionarily it seems like love would be an emotion that was developed so that we would keep mates. Seeing most animals, there are some exceptions, mate with different mates all the time then its hard to believe that they can love this mate or that one.

You have an airplane sitting on a moving runway (not fixed). The runway is like a treadmill, and it matches the speed of the plane but in the opposite direction. Can the airplane take off or not? Note that this is a tricky question.
