SixIf only the order is interesting (not the direction that they are oriented) then In the first place there can be any of the three, in the second place there can be either of the two left and then the last place is a given so: 3 * 2 * 1 = 6Six different orders for three people standing in a line.If their direction is also interesting to take into account (e.g. the middle person facing north while the others face east) then you have to know how many different directions and if standing on their heads counts as different etc.
The three points on a line form ONE line; the fourth point forms THREE additional lines, one with each of the first three points. So, four in total.
Yes. There can be a line perpendicular to the given line at every point on it, and you know how many different points there are on it ...

3 items (or people) can line up in 6 different sequences. 6 items (or people) can line up in 720 different sequences.
6 different ways

As long as at least two of them are different points, exactly one line.

If the people are always facing forward? 24 ways.
There are n! (n factorial) ways that n people can stand in line. So six people can stand in line in: 1*2*3*4*5*6 = 720 different ways
His do you get ”10” as the answer?
The conductors between a three-phase supply and a three-phase load are called line conductors not phase conductors, and the voltage measured between them are line voltages, not phase voltages. In the case of a delta supply, the line voltages are numerically equal to phase voltages, but the name remains the same!I have to admit that many people call line conductors 'phase conductors', but many people also say 'irregardless' -that doesn't make it a real word!!
