There are n straight lines in a plane, no two of which are parallel and no three pass through the same point. Their points of intersection are joined. The number of fresh lines thus formed is

There are n straight lines in a plane in which no two are parallel and no three pass through the same point.Their points of intersection are joined.Show that the number of fresh lines thus introduced is (1)/(8)n(n-1)(n-2)(n-3)

There are n straight lines in a plane in which no two are parallel and no three pass through the same point. Their points of intersection are joined. Show that the number of fresh lines thus introduced is 1/8n(n-1)(n-2)(n-3)

There are n straight lines in a plane in which no two are parallel and no three pass through the same point. Their points of intersection are joined. Show that the number of fresh lines thus introduced is 1/8n(n-1)(n-2)(n-3)

There are n straight lines in a plane in which no two are parallel and no three pass through the same point. Their points of intersection are joined. Show that the number of fresh lines thus introduced is 1/8n(n-1)(n-2)(n-3)

There are n straight lines in a plane in which no two are parallel and no three pass through the same point. Their points of intersection are joined. Show that the number of fresh lines thus introduced is 1/8n(n-1)(n-2)(n-3)

There are n straight lines in a plane in which no two are parallel and no three pass through the same point. Their points of intersection are joined. Show that the number of fresh lines thus introduced is 1/8n(n-1)(n-2)(n-3)

There are n is straight lines in a plane in which no two are parallel and no three pass through the same point their points of intersection are joined show that the number of fresh lines thus introduced is (1/8)n(n-1)(n-2)(n-3)

There are 10 straight lines in a plane no two of which are parallel and no three are concurrent.The points of intersection are joined,then the number of fresh lines formed are
