Thanks - It's for a proposition of an Adventure Resort on Mui Wo (school project) and the Internet doesnt come up with good suggestions.

I am at present working on a science fair project and as part of the project I have to use a transistor as a voltage amplifier. So can anyone tell me how to make a voltage amplifier, or just give me some URL's that relate to this subject. And don't just tell me "go and buy one" I have to make it myself.

What is the probability that the tallest and shortest are together? My own solution is [({6-2+1}-1)!2!]/[6-1]! = 48/120 = 2/5. But I'm not sure whether that's the solution. I know that number of ways of arranging n people in a circle is (n - 1)!.. But here I have 2 people who are supposed to be next to each other ie the tallest and shortest. In my numerator, i took 6-2 to remove the 2 people, add 1 to add in the 2 people who are now being considered as 1 group, -1 again cos of formula for permutation in a circle, *2! to permutate the people in the group. is that correct or do I have to apply the circle formula and take (2-1)! ? My instincts says the "2" doesnt have to be subtracted by 1 but can someone help me put it in a clearer perspective as to why we don't have to? And why do we have to take (n-1)! for permutations in a circle?
